 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.
