[cairo] Cairo, Python and GTK widgets within a context

[Donn]

Hi,
 Is there any way to "house" a GTK widget (say a button, or a text entry 
field) within a GDK DrawingArea (for which I can get a cairo context)?

I want to see if I can mix-in some GTK widgets and place them on the canvas. I 
am aiming at having them obey the matrix of the current context, so they can 
scale and rotate etc.

Any hope?
