A while ago I received an email from Nelson Castillo (sorry Nelson,
for not having replied sooner) who wrote a [non-Python] program that
does something similar to what you are describing.  The program can be
found at http://geocities.com/arhuaco/dfd.html
I have received a request to include something like what you describe
within rur-ple (wxPython based, rather than Tkinter).  I have
postponed looking into it seriously until version 1.0 of rur-ple
(realistically, not until the end of the summer).  I would be
interested in such a project - with the time constraint caveat.

Sorry that I can't be more helpful.
