This is because you are not running it as "root". From the "System" menu of KDE, run GKSu (you can also type "gksuexec" in a console). You will be ask for the name of the application you want to run, so type "qtparted". Then you need to enter the root password. If you run Knoppix from the CD then you should first set a root password manually see the second question in this FAQ http://www.knoppix.net/docs/index.php/FaqUsing
