wxPython stuff

So I got to try out wxPython, as I was earlier suggested. I got to try it out, and it was great! It really did feel like a Windows program and stuff. I took down some notes from the lacking tutorial wiki and I'm getting a small grasp of it, still learning... I still gotta find more hardcore detail about it.

Anyway, I just have one question...

Is the program I write using wxPython, just an interface shell, or is it still an integratable program, where I can do stuff deeper than just the interface, simply by coding it into the program itself, anyway?

Example:
import wx
(Here goes all the hoohah to make the interface)

x = 2


Would it only concentrate on what the interface is all about? or would it pick up 'x' that I can do commands with it? If it's possible, could this kinda thing be used with networking stuff like IRCs, MUGs, or whatever?

Thanks!
