Python based library integrated with Photoshop API

I would like to develop a plugin for Photoshop based on a algorithm that I found on github. The algorithm is coded in Python and I have read that integrating it to the Photoshop API (which is written in C/C++) is not so simple.

What do I have to know to start working on it? And what tools should I use? Developing a script instead of a plugin would be an easier alternative?
