Yes, you will need to know about C++ classes and object oriented
programming. But you really don't need to know the more difficult corners
of C++ (unless you decide to use QtConcurrent). OOP is the standard in all
GUI toolkits and frameworks, so it's good to know.

You don't have to make a clean break of Motif though. There is the Motif
Extension of Qt, that lets you mix Qt and Xt/Motif widgets and dialogs
together in the same program. This is by far the easiest way to go about
it. Currently it's only a commercial addon, I don't know if it will be
opensourced in the near future. See
