PyGTK is only for GTK 2, so you need to use PyGObject 3.x for 
introspection for GTK 3:


This doc is new, so you may need to fall back on the C docs + a bit of 


You may also needs to have introspection files for cairo so that 
PyGObject knows how to create pycairo objects.

I’m not very familiar with GTK (I use Pango and cairo without GTK) but 
apparently the magic function is gdk_cairo_create which returns a cairo 


As to OpenGL, I’m not sure what you mean. If you only want to draw in 2D 
with cairo, GTK chooses the backend so you don’t need to worry about it. 
For 3D stuff I don’t know.
