Good design, for one thing.  What business does a window have knowing
about graphs?  A window is a window is a window.  Same for a drawing
surface.  I've seen too many 3000-line CMyDialog: public CDialog classes
to buy the reuse-is-inheritance argument.

If you _really_ want to create a CMyWindow class, you can always use
aggregation.
