I already privately replied to Bill about this one, I said that I don't know if
Qt has easy bindings for OpenGL, and that the Qt license is so that if your app
isn't GPL, you will have to get a license from Troll Tech and it can be
expensive.
What I didn't say is that you have to pay to create OpenGL applications. You do
not have to pay to create OpenGL applications.
