how to theme/skin pyGtk apps

[binaryj]

hi again dear group.

what i am interested in is giving my pygtk app some distinct look, a
lil childish look coz the app is for children.

so, i downloaded a couple of themes from http://art.gnome.org/themes/gtk2/
and
for the past 1 hr i have been trying to theme my app but with no
results.

could anyone please guide me on who to theme pygtk and code samples
would be greatly appreciated

thanks
