Qt has been available under dual commercial or GPL license for years. 
Given that CCL is LLGPL, that should work.  CCL could bundle the GPL Qt 
and provide instructions for end-users to replace it with the commercial 
Qt as needed.

I've used Qt on mac, but never felt a desire to do gui work with the 
native tools...  The upcoming Qt 4.5 will be the first Qt version to use 
Cocoa.

IMO, the hard part is generating bindings to all the functionality Qt 
provides.  While most things can be handled through signals/slots, some 
are only available through subclassing.  This can be handled by subclasses 
which can register callbacks for each vtable entry.  There are too many 
things to do this by hand.  Hence the approach taken by Qt/Jambi, where 
hints are provided to guide an automated binding.


Just some thoughts,
