You have to release the source code of your own application. If you don't want to do that, you can buy a commercial license from Troll Tech. According to one of their people (on Freshmeat some time ago), they are doing this because they don't believe the GPL can be enforced against dynamic linking; if they get clear legal advice that a program dynamically linked against a GPL'd library must be released under the GPL (which is how the FSF intends it, as opposed to linking with an LGPL'd library), they would be willing to use the GPL for Qt too; but apparently their lawyers disagree with the FSF on the legal validity of this, and it hasn't been tested in court.
