No, there is a free (as in freedom) version of Qt:
"The KDE Free Qt Foundation is an organization with the purpose of securing the availability of the Qt toolkit for the development of Free Software and in particular for the development of KDE software. It was originally founded by Trolltech and the KDE e.V. in 1998. After Nokia bought Trolltech, statutes were updated accordingly."
