So my question is how to communicate from Python to the C module on the PC. What I'd like is simplicity and ease of setting up. All I can think of myself is to use sockets.

Have a look at Cython:

This enables you to call C code from Python code within the same process.

I assume that by "PC" you mean Windows in which case mingw is a fine
choice and is officially supported by Cython.
