graphical designer for Qt3 applications

 The Qt Designer is a GUI design program that interactively lets you
 construct user interfaces for the Qt library. Additionally it lets you
 create whole project and works together with the database drivers
 provided by Qt to create applications with easy database access through
 Qt. The resulting user interface files can then be converted to
 C++ classes using the uic commandline utility which is usually done
 automatically for the developer with a project management with qmake
 or automake.
