I don't think there's anything wrong with it. The main thing to
remember is to try to keep the interface and the logic separate. I
have a fairly complex program with lots of tabs and sub tabs. So I
stuck each of the tab's display code in a separate file and imported
them into my main program.

One good place to learn from would be the wxPython demo. See how Dunn
et al did it with that. Or check out Editra's source. I know there's a
few wxPython-istas that love XRC for the GUI layout stuff, so that's
an option too. I don't use it myself as I couldn't figure out how to
implement some of the widgets with it.
