Hi Joe,
I haven't seen your message about this on Tutor yet; have you reposted
your question there? I'm still a bit busy and haven't had a chance to
look at this thoroughly; the others on Python-tutor should take a look at
this.
If I understand your program, it appears to be a mineral or material
hardness reference program? It may be nice to organize the data to make
it easier to extend. Concretely, it looks like the program is dealing
with hierarchical data:
Materials
Aluminum
Wrought
Die Cast
Sand Cast
Steel
Low Carbon
Medium/High Carbon
Alloy
...
and so keeping this data in a hierarchical data structure seems like a
useful thing. Even something simple like:
{ 'Aluminum' : ['Wrought', ...],
'Steel', : ['Low Carbon', ...] }
could be a first step in distilling out the interesting data from your
program into a single place. At the moment, that knowledge seems spread
out in the individual GUI elements, and it seems difficult to add more
information without modifying several parts of the code.

It'll take both practice and feedback from others to get more comfortable
with program design. Feel free to post your code on the mailing list to
get feedback.
Good luck!
