Nokia announced today http://www.qtsoftware.com/about/news/lgpl-license-option-added-to-qt that Qt-4.5 will be licensed as LGPL (Lesser General Public License). This puts Qt on the same footing as gtk and will certainly increaseQt usage great deal. Some other scripting languages such as Python and Ruby already have mature Qt bindings.
I am curious whether Qt Lua bindings are being actively developed? --Leo--
