Tk is a cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. It is free and open-source software released under a BSD-style software license.
Tkinter is a binding to the Tk GUI toolkit for Python. It is the standard Python interface to the Tk GUI toolkit, [1] and is Python's de facto standard GUI. [2] Tkinter is included with standard Linux, Microsoft Windows and macOS installs of Python. The name Tkinter comes from Tk interface.
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [ 1 ] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...

GNUstep contains a set of graphical control elements written in the Objective-C programming language. The graphical user interface (GUI) of GNUMail is composed of graphics control elements. GNUMail has to interact with the windowing system , e.g. X11 or Wayland , and its graphical user interface has to be rendered .
FLTK is an object-oriented widget toolkit written in the programming language C++. While GTK is mainly optimized for the X Window System, FLTK works on other platforms, including Microsoft Windows (interfaced with the Windows API), and OS X (interfaced with Quartz). A Wayland back-end has been implemented and is available since release 1.4.0. [5]
The choice of a variable name should be mnemonic — that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters. int i;
In computer programming, a window class is a fundamental in many windowing systems, including the Microsoft Windows (Win16, Win32, and Win64) operating systems, IBM OS/2 [1] and the X Window System. [2] The class defines the window procedure used tp process messages for all windows created with that class. [1]
