GWindows in fact offers both and it works out very nicely. GWindows strikes
a good balance in its "subscriber" model of events by just basicly offering
a simple call back registration mechanism removing most of the complexities
of programming in that model. For more complex work the override model can
be used to easily offer more.

GtkAda is a nice solution for many problems, but if you are looking to be
native to Win32, it doesn't cut the mustard.
