How to add UI to the windows8.1 window (C++/CX) - windows-8.1

Question

I've got the most simple windows store program. It just runs the white-color window till the Quit (as well as the most simple Win32 application would do).
ref class ApplicationViewSource sealed : IFrameworkViewSource {
public:
virtual IFrameworkView^ CreateView() {
return ref new WindowsStoreApp::MainView();
}
};
[MTAThread]
int main(Array<String^>^ args) {
CoreApplication::Run(ref new ApplicationViewSource());
return 0;
}
ref class MainView sealed : IFrameworkView {
public:
virtual void Initialize(CoreApplicationView^ AppView);
virtual void SetWindow(CoreWindow^ Window);
virtual void Load(String^ EntryPoint);
virtual void Run();
virtual void Uninitialize();
void OnActivated(CoreApplicationView^, IActivatedEventArgs^);
};
void MainView::Initialize(CoreApplicationView^ AppView) {
AppView->Activated += ref new TypedEventHandler<CoreApplicationView^, IActivatedEventArgs^>(this, &MainView::OnActivated);
}
void MainView::SetWindow(CoreWindow^ window) {
window->PointerCursor = ref new CoreCursor(CoreCursorType::Hand, 0);
}
void MainView::Load(String^ EntryPoint) {
}
void MainView::Run() {
CoreWindow::GetForCurrentThread()->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessUntilQuit);
}
void MainView::Uninitialize() {
}
void MainView::OnActivated(CoreApplicationView^, IActivatedEventArgs^) {
CoreWindow::GetForCurrentThread()->Activate();
}
So... What I need to do next ? As for Win32 project I could create some graphical user interface components with CreateWindow(Ex) function as windows of the specific window-classes. With the windows store app API I can't figure out how to add any visuals.
Manual only gives hints about adding ones with code to existing XAML page, allready been connected to the window.
