What’s Qt you ask? Qt is a cross-platform application and UI framework which enables you to create a better user experience. Using Qt, you can write applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code. Qt has an intuitive C++ class library and includes integrated development tools with a cross-platform IDE. Visit the Qt website for more details: http://qt.nokia.com.
