Let's take a look at what three difference, modern, OO GUI API's have done:

3) Cocoa: Apple co-opted an existing language. Once again, a delegate
model enters the picture for people who want to tweak the
functionality of a control without completely subclassing it. But I
think Obj-C wins over the others because of the category support,
which allows you to add methods without subclassing.
In each case these guys looked at what C++ had to offer. They looked
at the failure of MFC. And then they decided to go down a different
road. To me that's pretty convincing evidence that the
Carbon/Win32/gtk style APIs are not up to task, and that C++ is not
the best language to build a new one on.
Many of the basic design decisions for Cocoa came over unchanged from NeXTstep,
which was designed in the mid 1980s - predating C++.
Calling Objective-C "modern" is about as accurate as calling Unix "modern" ;-)
