Most people believe that extending Python (Python calling C code) is much
easier and much better than embedding Python (C code calling Python code). It's
possible to embed, but it's a real pain in the butt (I know, I tried it.)
Anything too slow to run in Python can be done in C, and there's a library
called Psyco (psyco.sourceforge.net) that you'll definitely want to look at
(it's sort of a JIT compiler). Psyco's not a panacea, but it sure as heck can
help. This is the approach I'm using for my own game design, which is an RPG.
(By the way, I find XML DocBook to be a great format to write design documents
in, if you're also a designer.) Because most of the execution is in such a
small portion of the code, it shouldn't be a big deal.

wxPython is what you want. http://wxpython.org/

I'm not sure how you'll manage to use Python code without giving the Python
source in some for. You could distribute .pyc files, but I think they could be
reasonably decompiled (not sure).
