Qt- C++ GUI library

Qt is a multiplatform C++ GUI toolkit created and maintained byTrolltech. It provides application developers with all the functionality needed to build applications with state-of-the-art graphical user interfaces. Qt is fully object-oriented, easily extensible, and allows true component programming.

Since its commercial introduction in early 1996, Qt has formed the basis of many thousands of successful applications worldwide. Qt is also the basis of the popular KDE Linux desktop environment, a standard component of all major Linux distributions.
