Three ways of doing this:

1. Turn your C program into a library, and write a Python extension
   module to interface it.

2. Embed Python in your C program.

3. If you're talking command-line programs, you can interface the
   compiled programs with the subprocess module.

For (1) and (2), start with the Extending/Embedding section at
http://docs.python.org/py3k/ (or http://docs.python.org/). With (1),
using Cython or SWIG might make writing the "glue" between Python and
your C code easier.

For (3), check the docs of the subprocess module.

It might, however, be best to simply write the GUI in C as well, which
would avoid the overhead of loading Python and isn't all that difficult
either. If you know C++, check out wxWidgets and Qt4. To stick with
plain C, have a look at GTK+.
