Tkinter vs PyGTK

[JyotiC]

I want to make a stand alone gui. Whose work is to get the diff options
from user and run a shell  script based on them.

I wanna know which one is better to use Tkinter or PyGTK, in terms of
efficiency and functionality.

I hv read about Tkinter, but it takes too much time to  load, is there
a way to make it faster.
Is all gui take more time to load, this is the first time i am making a
gui.
wIll PyGtk be faster.
Is there any other way of making a gui using python

Thanx in advance
