No, language bindings have to be GPL'd. But you can dual license it so that 
holders of commercial licenses can do commercial things with it if you want 
(eg an MIT license).

You also have to be careful about including 'qt' in the name of your project. 
I had a mail from Trolltech's legal department about QtRuby 'diluting the 
brand', and would I rename my project. I told them I thought that was a bit 
unreasonable, and we agreed in the that I include this text in the 'COPYING' 


"[QtRuby": "[Qt]" name usage by permission of Trolltech AS, owner of the 
Qt(TM) trademark

Which is why I called the C# bindings project 'Qyoto' to avoid any similar 
trouble. But I can't imagine Trolltech ever wanting to do a php bindings 
project though, so you shouldn't have any problem.
