Correct abstraction for TK

[luke.hoersten at gmail.com]

I'm looking for a good example of how to correctly abstract TK code
from the rest of my program. I want to just get some user info and
then get 4 values from the GUI. Right now I've written it OOP per the
examples on python.org but it doesn't seem to be meshing very well
with the rest of my project.

Can anyone suggest some examples so that I can get more ideas?

Thanks,
Luke
