To create organization (this is from seven-cogs StartupAction.java)
long userId = defaultUserId;
long parentOrganizationId = OrganizationConstants.DEFAULT_PARENT_ORGANIZATION_ID;
String name = "7Cogs, Inc.";
String type = OrganizationConstants.TYPE_REGULAR_ORGANIZATION;
boolean recursable = true;
long regionId = 0;
long countryId = 0;
int statusId = GetterUtil.getInteger(PropsUtil.get("sql.data.com.liferay.portal.model.ListType.organization.status"));
String comments = null;
ServiceContext serviceContext = new ServiceContext();
serviceContext.setAddCommunityPermissions(true);
serviceContext.setAddGuestPermissions(true);
Organization organization =
OrganizationLocalServiceUtil.addOrganization(
userId, parentOrganizationId, name, type, recursable, regionId,
countryId, statusId, comments, serviceContext);
Group group = organization.getGroup();
GroupLocalServiceUtil.updateFriendlyURL(group.getGroupId(), "/7cogs");
Are you sure that you need two organizations and not two communities?
UPDATE for question in comment:
To get organization name in theme (velovity) you can use (if you are in organization's pages (group))
In portal-ext.properties
journal.template.velocity.restricted.variables=
In theme vm file
Liferay 6
#set($os = $serviceLocator.findService("com.liferay.portal.service.OrganizationLocalService"))
#set($organization = $os.getOrganization($themeDisplay.getScopeGroup().getOrganizationId()))
$organization.getName()
Liferay 5.x
#set($os = $serviceLocator.findService("com.liferay.portal.service.OrganizationLocalServiceUtil"))
#set($organization = $os.getOrganization($themeDisplay.getScopeGroup().getOrganizationId()))
$organization.getName()
EDIT:
If your user is member of organization(s) than you can use
#foreach($org in $themeDisplay.getUser().getOrganizations())
$org.getName()<br>
#end
Take note that user can be member of multiple organizations and you will get all of them.

What you need to know about the code:
From the same class Martin mentioned I've put together a mix of code that will achieve what you need.
Note that some of the variables are not defined. You'll have to use the correct values that are particular to your Liferay installation. For example, the userId could be anyone but I would suggest using either the default user's userId or an administrator's userId.
The Code:
Organization organization =
OrganizationLocalServiceUtil.addOrganization(
userId, OrganizationConstants.DEFAULT_PARENT_ORGANIZATION_ID,
"My Org 1", OrganizationConstants.TYPE_REGULAR_ORGANIZATION, true,
regionId, countryId, statusId, comments, true, serviceContext);
Group group = organization.getGroup();
GroupLocalServiceUtil.updateFriendlyURL(group.getGroupId(), "/cat1");
LayoutLocalServiceUtil.addLayout(
group.getCreatorUserId(), group.getGroupId(), "false",
LayoutConstants.DEFAULT_PARENT_LAYOUT_ID, "My Link 1", StringPool.BLANK,
StringPool.BLANK, LayoutConstants.TYPE_PORTLET, false, "/link1",
false, serviceContext);
LayoutLocalServiceUtil.addLayout(
group.getCreatorUserId(), group.getGroupId(), "false",
LayoutConstants.DEFAULT_PARENT_LAYOUT_ID, "My Link 2", StringPool.BLANK,
StringPool.BLANK, LayoutConstants.TYPE_PORTLET, false, "/link2",
false, serviceContext);
organization =
OrganizationLocalServiceUtil.addOrganization(
userId, parentOrganizationId, name, type, recursable, regionId,
countryId, statusId, comments, true, serviceContext);
group = organization.getGroup();
GroupLocalServiceUtil.updateFriendlyURL(group.getGroupId(), "/cat2");
LayoutLocalServiceUtil.addLayout(
group.getCreatorUserId(), group.getGroupId(), "false",
LayoutConstants.DEFAULT_PARENT_LAYOUT_ID, "My Link 3", StringPool.BLANK,
StringPool.BLANK, LayoutConstants.TYPE_PORTLET, false, "/link3",
false, serviceContext);
LayoutLocalServiceUtil.addLayout(
group.getCreatorUserId(), group.getGroupId(), "false",
LayoutConstants.DEFAULT_PARENT_LAYOUT_ID, "My Link 4", StringPool.BLANK,
StringPool.BLANK, LayoutConstants.TYPE_PORTLET, false, "/link4",
false, serviceContext);
