Take a look at the source for the turtle module (in
Python/Lib/lib-tk/turtle.py I think). It has a global _root object
which is the Tk instance.

You could make your own Pen class, subclassing from RawPen, that makes
whatever kind of window you would prefer. Then instead of using the
module functions forward(), down(), etc - which just delegate to a
global Pen instance - make an instance of your own pen and draw with
that.
