3D plotting in a GUI

[Baris Demir]

Hi all,

I need to develop a GUI for some scientific data processing operations 
and this GUI should work well with a 3D plotting module, also with NumPy 
and SciPy for sure. I made a search about packages but, there are plenty 
of these modules available. What kind of a package or a package of 
packages might be the best way  for this  work. BTW I do not want to use 
MayaVi. It is too much actually.

Thanks in advance.
