Interface Builder Problem

Hi,
I am new to the list, so please forgive me if my question has been
answered recently.
Now my problem: I am porting a small application (Gomoku.app) from
GNUstep to Cocoa. While this app uses "hardcoded" menus under GNUstep, I
want to use a nib for the menus. So I created the menus in IB and
changed the already existing menu actions from (void) to (IBAction) in
the .m file  and added IBOutlets to the corresponding header file.
Then I imported that class via Read Files from the Classes Menu into
Interface Builder. All IBActions and IBOutlets were recognized properly.
Then I tried to Instantiate that class to make the connections between
the menu and the class. This was not possible since that menu-item of IB
was grayed out. Another class of that project did instantiate without
problems. The difference of that two classes is that the first is a
subclass of NSWindow and the later of NSObject.
How do I instantiate a class in IB that is not a direct subclass of
NSObject?

Thanks in advance, Lars
