Qt is a cross-platform application framework for building graphical user interfaces. It provides tools to develop applications that work on multiple desktop and mobile operating systems. Qt uses C++ and offers APIs for developing applications with classic or QML-based user interfaces. It includes modules for GUI, widgets, networking, multimedia, and more. Popular Qt tools include Qt Creator for development, Qt Designer for layouts, and Qt Linguist for translations. Qt sees wide use for applications across domains like embedded systems, mobile apps, and desktop programs.

2. Introduction

 A graphical user interface is the system by which users interact
with a machine.
 The user interface includes hardware (physical) and software
(logical) components. User interfaces exist for various systems, and
provide a means of:
 Input, allowing the users to manipulate a system
 Output, allowing the system to indicate the effects of the users'
manipulation
 QT can help providing a good quality graphical interface.

 APIs for C++.
 QT gives developers the ability to build better native applications
on mobile, embedded and desktop devices more efficiently .
 It was called Qt because the letter Q looked appealing in Haavard's
Emacs (developper) typeface, and "t" was inspired by Xt, the X toolkit.
