[visionegg] newbie question about GUI experiments

Hi, 
 
I am new to both the Python progamming language and VisionEgg. I need to
program an experiment and would like to know if VisionEgg can do what I
need. The experiment is a study of how users interact with a GUI. It is at
much higher level than the type of experiments done in psychophysics, which
VisionEgg was designed to run (as I understand it). So, I have at least two
problems to solve. First, I need to create the GUI and define the methods
for interacting with the user. Ideally, I need methods for button responses
to both mouse clicks and keypresses. It seems that this can be done in
Python with either the Tkinter or wxPython module. Is that right? Moreover,
it does not seem as if I can build a GUI using tools in VisionEgg itself? Is
that right? My second problem is timing. As the user interacts with the GUI,
I want to record with millisecond precision the time at which events occur.
Would displaying the GUI with VisionEgg, if possible, enable the kind of
temporal precision I require?
 
Thank you for any help you can provide,
Steve Lacey
