I think an NSMatrix of buttons would work here. In IB, option-drag one of
the button handles so that you get your desired number of buttons. Set the
tag for each individual button so that you can reference each one. Then
connect the NSMatrix to the action method. Inside your action method you can
determine which button was clicked using something like this:

- (IBAction) myAction: (id) sender
{
if ([sender selectedTag] == 0)
{
// First button was clicked
}
}
