We've done this using aliens in Newspeak (see ObjectiveCAline and friends). To 
do a real GUI is more involved, because of MacOS threading issues (which thread 
is in control etc.). We hope to fix this in time, and of course provide a fully 
native binding for the Brazil/Hopscotch GUI on macs, as we do on Windows.

Inteoperating smoothly with the rest of the world is very useful.
