This looks promising too:

The problem I'm having right now is trying to figure out how to access  
classes that aren't loaded into the Cocoa app by default (like  
QCView).  I've built and loaded the :quartz interface directory, but  
the analog of (make-instance 'ns:ns-view) still doesn't work.  I'm  
digging through the sources to try to figure out how ns:ns-view gets  
set up to try to do something analogous for qc:qc-view.
