What is a GUI?

GUI or Graphical User Interfaces were developed in the late 1970s by Xerox Palo Alto research laboratory. They were deployed in Apple’s Macintosh and Microsoft’s Windows operating systems. Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities. The Xerox system is still in use today.

How Does a Graphical User Interface Work?
Graphical user interface design principles conform to the model–view–controller software pattern. Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the task.

Advantages of Graphical User Interfaces
Graphical user interfaces leverage familiar metaphors, such as drag-and-drop for transferring files, and use familiar icons. Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability. The advantage of a graphical user interface is stark improvement in usability for the average person.

Best Programming Language for Graphical User Interfaces
C# and Java may be considered preferable options for the development of a graphical user interface design. C# allows you to run GUIs simultaneously in a browser and as a desktop application. Other options include Python, HTML5/Javascript, and C/C++.
