Qt is a cross-platform application framework used for developing software with a graphical user interface (GUI) as well as non-GUI programs such as command-line tools and consoles. It provides tools for creating applications that can run on various hardware and software platforms without modification of the source code.

About Qt
Qt was created in 1991 by Haavard Nord and Eirik Chambe-Eng. It was developed to provide a robust framework for cross-platform software development, allowing developers to write applications that could run on multiple operating systems without needing to alter the source code.
Strengths of Qt include cross-platform compatibility, extensive documentation, and a comprehensive set of tools for both GUI and non-GUI development. Weaknesses include a steep learning curve and potentially high licensing costs for commercial use. Competitors include GTK, wxWidgets, and Electron.
