GTK4/GObject in C Tutorial - Part 1 - Introduction

First part of a tutorial explaining how to use the GObject system with GTK4, in C. Here, we start by creating a simple (but useless) custom widget. Note that this is a re-recording of the original video. The original video can still be found on my channel, suffixed with "(OLD VERSION)".
