The Trolltech website is pretty clear on such matters as it *is* their bread 
and butter :-)

In short:
Trolltech does not sell a royalty (i.e., each copy needs a license) based 
license for Qt.  The licenses are tied to developers.  So if your company has 
5 people actively working on the Qt part of the code, then you'll need to get 
5 licenses.  There are actually three factors that determine how much the 
licenses are going to be:
1. How many developers need licenses?
2. Are you developing for just Window, just X11, or both?
3. What "extra" features (like XML, DB, etc) do you need?

Same here.  One thing to note, though: If Qt isn't an option due to its price 
and you find yourself being pushed towards Gtk+, do yourself a favor and 
check out wxWidgets.  wxWidgets is a cross-platform C++ toolkit that compares 
fairly favorably with Qt.  It's not as polished, but it's FAR better than 
most of the alternatives.  It uses Gtk+ as the backend under X so you get all 
of the benefits of Gtk+ without the horrific API.
