Working a lot right now on the 
[Tix] Integrated Development Environment:
http://starship.python.net/crew/mike/
which includes 

[IDEStudio] [SpecTix] [TixXf] and [TixClips],

TIDE is built on the [Tixapps] framework 
http://tix.sourceforge.net/Tixapps/ which is a library and suite
of programs which work as either Tcl or [Tkinter] applications.
