looking for gui for python code

[devnew at gmail.com]

hi
i have written some python scripts which take command line arguments
and do some job. i would like to make it into a .exe using py2exe and
distribute it with innosetup.. befor that i would like to add some GUI
support..i mean select some values using a folder explorer etc..which
would be a good gui builder for this? i have heard about  guibuilder
from http://spectcl.sourceforge.net/  or is it better to use tkinter
(i have little experience with gui designing)

can someone  give a suggestion?
TIA
dn
