GTK (GIMP Toolkit)

GTK, or GIMP Toolkit, is a set of software tools used to build graphical user interfaces (GUIs) for applications. Think of it as a collection of building blocks that developers use to create windows, buttons, menus, and other visual elements on your screen. It simplifies designing consistent, functional interfaces across different operating systems like Linux, Windows, and macOS. GTK is open-source, highly customizable, and widely used in applications such as the GIMP image editor and various Linux desktop environments. It helps make software more user-friendly by providing a cohesive and responsive visual experience.
