You can't avoid coding in C completely, but you can cut down on the amount
of work tremendously.

What you need to do is write a C DLL. The DLL will implement your API.
Inside the implementation, use the Python API to call from the DLL into your
python code. Essentially embed Python into your DLL. The original app will
just call the DLL and not know that python's involved at all, and you can
write your actual logic in Python.
