Tkinter for system administration?

[Dave Benjamin]

Is Tkinter pretty common for simple behind-the-scenes admin tools where 
a GUI is required (for instance, data entry tools for non-programmers) 
or has everybody moved on to wx/GTK/QT/etc.?

I'm not particularly concerned with speed or appearance; the ability to 
crank out simple GUIs quickly and without a lot of hassles or trips to 
the reference manual is more important. I have no trouble using Tkinter 
because I used to write a bit of Tcl/Tk back in the day, and I'm pretty 
aware of its strengths and weaknesses. For simple tools, is there any 
reason to switch to one of the more popular GUI frameworks?

Thanks,
Dave
