If you have time, I would recommend doubg some reading about
some of the classic GUI design paradigms such as model-view-presentation
where messages are passed around between objects to do tasks.
I forget now if it is MnVP or MVnP (where n represents a
many to many relationship.)  Some of these designs are not
quite as efficient as others.  Oh, this applies more to Java
and eiffel (both strong object based languages) than C/C++.
