Ah fine, please do so - (and keep us informed).
There is one single class, TurtleScreenBase, which contains the 
interface to Tkinter. It was
one of my primary design decisions, to keep this small and isolated. (I 
had in mind e.g. porting
it to Jython). So at first concentrate on that small part of the thing.

Unfortunately this part of the software is still not very well 
documented (albeit it doesn't
contain special intricacies). If you have questions, feel free to ask.

(Of course that doesn't apply to the demoViewer ...)
