I think the main thing is to follow Model/View/Controller (MVC)  
design principles as much as possible. For information on how to do  
this, I'd highly recommend you get Robin and Neil's "wxPython in  
Action" book and read chapter 5, which actually shows a complete  
example of taking a "standard" application and refactoring it to use  
MVC design principles.

I would also recommend that you consider looking at unit testing and  
Test Driven Development (TDD). I can't stress enough that writing  
tests for your code as you develop it greatly improves reliability,  
and also encourages modular design. This is also covered to a degree  
in chapter 5, and there's some more info on these subjects on the web.

Regards,

Kevin
