A suggestion, avoid doing it like Java.

To do it like java, you first have to write an event dispatcher,
and then have your objects wait on IPC.  Java's event model is 
heavily thread oriented, and makes sense for that language, but
not as much when threading is done on say a process level.

If you are writing something in C, you are probably better off
with callback lists which gui elements register for, as with
typical X programming.  If you are doing this in C++ its not
that hard to write an interface class to handle all this, and
then derive the various event types.

These two approaches may simply seem semantically different, but
that is because the java class libraries have hidden the nasty
interface to the underlying event system from you...
