I think you can directly crate a dialog box something like this..
<p:commandButton id="basic" value="Basic" onclick="dlg1.show();" type="button" />
<p:dialog id="basicDialog" header="Basic Dialog" widgetVar="dlg1">
<h:outputText value="Resistance to PrimeFaces is futile!" />
</p:dialog>
If you are using Primefaces then i dont thing we have to create a dialog box manually we can use their component it will increase productivity and bug fixing time
