I'm curious about how to actually implement an immediate mode GUI (IMGUI) library. I've looked around but haven't found any great tutorials, whether they be text or video. I've got no experience in building UIs, let alone libraries for them, but I'm eager to learn. It would really help if anyone could point me towards resources or guides that explain the implementation of an IMGUI, preferably in C or Go since those are the languages I'm familiar with. Examples would be a bonus!

It sounds like you're trying to create the IMGUI library itself, right? That can definitely be a bit tricky since most tutorials focus on using these libraries rather than building them. If you're new to this, I'd suggest looking into graphics programming basics first, as IMGUI is closely tied to rendering. Once you have a grasp on that, there are books like "Game Engine Architecture" that touch on GUI systems. Also, checking out GitHub for open-source IMGUI libraries might help you understand how existing ones are structured.
Definitely check out examples on GitHub! You can see how other developers tackled implementation issues and learn from their code. Also, consider checking sites like Medium or dev.to where many developers share their experiences and insights into creating UI libraries.
