Qt is a C++ toolkit for cross-platform GUI and
application development. In addition to the Qt
C++ class library, the toolkit includes tools like
Qt Designer that make writing applications fast
and straightforward. Qt’s multiplatform abilities
and internationalization support means that Qt
applications can reach the widest
market.
