SWIG can provide access to wxWidgets and a lot of other stuff. TASH can 
also be considered. May be Visual Ada Designer can be ported to Mac OS 
X. Tcl/Tk on Mac OS X has some i18n issues. The same as X11. User can't 
change keyboard layout via hotkeys (Command-Space usually). The only way 
to change layout in X11 apps is to use Input Menu (similar to Language 
Bar in Windows). Constantly clicking while typing is inconvenient for 
non-English users so X11 (and Tcl/Tk) applications are very unpopular. 
But it is solveable. I've maid a patch for Apple X11 to enable hotkeys 
and the same could probably be done for Wish Shell.

I don't think mixing semantics is a good idea. It's OK for C languages 
family to be a frankenstein, but not for Ada.

An absolutely blank project already exists on Google Code called Cocoa-GNAT.

Provided that:
a. Cocoa is a superset of OpenStep
b. BridgeSupport files are automatically generated from headers

One might try to either get a subset of Cocoa metainfo or use modified 
generator on GNUStep headers.
