Qt is a cross-platform application framework that is widely used for developing application software with graphical user interface (GUI) (in which case Qt is referred to as a widget toolkit when used as such)

Qt uses standard C++ but makes extensive use of a special code generator (called the Meta Object Compiler, or moc) together with several macros to enrich the language. Qt can also be used in several other programming languages via language bindings. It runs on all major platforms and has extensive internationalization support. Non-GUI features include SQL database access, XML parsing, thread management, network support, and a unified cross-platform API for file handling.

Distributed under the terms of the GNU Lesser General Public License (among others), Qt is free and open source software

Qt is released by Nokia on the following platforms:

Linux/X11 – Qt for X Window System (GNU/Linux, HP-UX, Solaris, AIX, etc.)
Mac OS X – Qt for Apple Mac OS X. Support for applications on top of Cocoa APIs
Windows – Qt for Microsoft Windows
Embedded Linux – Qt for embedded platforms (PDA, Smartphone, etc.)
Windows CE / Mobile – Qt for Windows CE
Symbian – Qt for the Symbian platform. Qt is to replace Nokia's Avkon as the supported UI SDK for the development of Symbian applications. The Qt for Symbian development group has many quality-controlled articles available.
Maemo – Qt for Maemo, merged with Moblin to MeeGo. There are many applications already written for Maemo based on the previous Internet Tablets. The Nokia N900 also supports Qt. The Forum Nokia Wiki has quality-controlled articles that support Qt development. The Maemo operating system has a development group on the Forum Nokia Wiki at Forum Nokia Wiki Maemo.

Since Nokia opened the Qt source code to the community on Gitorious various ports have been appearing. Here are some of them:

Qt for OpenSolaris – Qt for OpenSolaris
Qt for Haiku – Qt for Haiku OS
Qt for OS/2 – Qt for OS/2 eCS platform.
Qt-iPhone – Experimental development of Qt for the iPhone.
Android-Lighthouse – Experimental development of Qt for Android.
Qt for webOS – Experimental development of Qt for webOS on Palm Pre.
Qt for Amazon Kindle DX – Experimental development of Qt for Amazon Kindle DX.
Qt for Wayland – Experimental development of Qt for Wayland display server, could be used in Intel's MeeGo Touch.
