need help with an accessibility prototype

[Eric S. Johansson]

2 needs.  first is determining if NaturallySpeaking injects keycodes or 
ascii char into the windows input queue.  second is building a test 
widget to capture and display text.

I think I can solve both of these by building a simple text widget 
(tkinter? qt? ??) to capture keycodes.  problem, is in <mumble><mumble> 
yrs of programming, I've never written a GUI interface so I have no idea 
where to start.  help, tutor, pointers to samples would be most welcome.
