Qt Creator is an integrated software development environment that supports both traditional C++ application development as well as development using the Qt project's libraries (collectively called Qt and pronounced as cute).
Qt is available under a commercial license as well as under GPL v3 and LGPL v2. Its development dates all the way back to 1991. For the first ten years of its life, it was a cross-platform toolkit for Windows and X11; by 2001, support for Mac OS X was added.
