I know that there is a package for Pygtk demos (sudo apt-get install gtk2.0-examples) but I can't found an equivalent one for PyGObject.

There's no packages providing the pygobject
examples, you can check the individual binaries file listing here, all built from the pygobject
source package.
However they are available in the git repo:
There are examples for many of the GTK controls at: http://python-gtk-3-tutorial.readthedocs.org/en/latest/
I find Geany to be a handy IDE for this since you can just paste in and click run.
