Mac OS X choices

[Alex Lindsay]

I have been using RealBasic and Valentina for some personal projects 
and I am considering doing some work in Cocoa (Objective C).  What 
Valentina product would be best?  Should I look at the C libraries or 
the C++ classes?  I know that the X Tools compiler has Objective C++ 
(Objective C with some C++) support but I am unsure of the real world 
issues involved in mixing the two.  I am very familiar with both 
straight C as well as C++.   Is there any Object-C wrappers for 
Valentina?

I would be interested in any and all experiences with Valentina in a 
Mac OS X.
