Simple Pygame GUI (SPG) is a very simple and fast GUI library for PyGame. It's a very high level library, very easy to use and setup, but still good-looking and pretty advanced.
This is the second version of an older still library written by me (keebus) some time ago. I wanted to recreate it from scratch, using a more beautiful coding style and adding extra features that were not planned for the first version.
It is still in early development stage, but the core mechanics have been made, as well as some of the important Widgets, as the Button and Window widget. It already runs pretty fast.
