Merry Christmas! The look is very similar to DrPython's, which was also designed for teaching purposes (I think it was a python version of a DrScheme (now DrRacket) related to how to think like a computer scientist). He could perhaps start with DrPython's GUI.

Edit: hm, DrPython is in wxpython. They need a tkinter version of the same GUI.
