[pygtk] building pygtk applications using python3.1

[goli]

Hi all,

I am a newbie to the python language, I used pygtk with python2.6 for a 
week, now I want to switch to python3.
I installed python3.1 and wrote a simple app to test it using pygtk. but 
python compiler says that it can't import pygtk.
I reinstalled python bindings for gtk (python-gtk on ubuntu), but no 
modules added for python3.
Is it really possible to use them together, or am I missing some points?
Thanks.
