Are there any good examples to look at?
Also is there anything you need to do to prevent the the main window 
from being locked ot a minimum size?
I noticed that when a re-positioned a child widget with

gtk_fixed_move or gtk_widget_set_size_request() that the minimum width/height of the main window 
would be affected, preventing the user from resizing it less than the child current pos.

When implementing the methods for the container how do you move the widget (other than the above mentioned gtk_fixed_move or gtk_widget_set_size_request )?
