Coding a Graphical User Interface in C - from scratch

YouTube Excerpt: "Code a GUI from scratch in C! Build a 2D graphics engine & display custom windows in this epic 2-part tutorial. Subscribe now!" Welcome to the "Code a GUI in C project! In this self-contained tutorial, we’re building a custom Windows-like system from the ground up. You’ll learn to code a 2D graphics engine, design a graphical user interface (GUI), and display real windows on-screen with mouse controls—all in C! We’ll run everything in a virtualized environment (works on Windows, Linux, or Mac OS X, with easy setup instructions included). What You’ll Learn: ✅ Part 1: Design the interface, code a 2D graphics engine from scratch, handling text, points, lines, and rectangles. ✅ Part 2: Parse the .BMP file format to draw pixel-perfect images for your GUI’s window designs. Prerequisites: Basic C knowledge is needed, but don’t worry—additional components are minimal (just 5% of the project), and you can copy them if needed. The full source code is available for free at my code repo (linked below, available for 4 days as usual). Comment below: What’s your dream GUI project?
