I think this could be helpful for you:

This is tkCairo extension in work. You can find the code in our repository:

http://sk1.svn.sourceforge.net/viewvc/sk1/trunk/subprojects/tkCairo/

tkCairo is modified pycairo project for tk widgetset. So you can use pycairo
docs
as a cairo command reference. Please note we have implemented Linux support
only.
But this extension can be easy adopted for win32.

Concerning tk Frame stacking you can try using place() manager. All tk
widgets are
native windows without WM decorations. So you can apply all toplevel methods
to widgets if they managed by place() manager.
