There's no difference between using C and C++. Obviously, you always
need the correct extern "C" declarations, but IIRC, Python's method
definition macros handle that.

You could convert your whole application to a Python extension module,
expose the main function to Python, and launch the program using a small
Python wrapper script. (Or you could embed Python in your application.)
