As mentioned above, wxApp::OnInit() is called upon startup and should be used
to initialize the program, maybe showing a "splash screen" and creating the
main window (or several). The frame should get a title bar text ("Hello World")
and a position and start-up size. One frame can also be declared to be the top
window. Returning @true indicates a successful initialization.

creating their child windows before showing them, we also need to explicitly
show it to make it appear on the screen. Finally, we return @true from this
