I'd always say make them from scratch since the existing mod creation tools like MCreator have limitations that make them impractical for big projects. You have more creative freedom without those limitations, plus the source code that MCreator generates is quite clunky from what I've heard.

Fortunately though Java is a great language to pick up and learn quickly, especially if you have prior experience in other programming languages. Started learning it recently at uni and I've been amazed at how powerful it is, especially coming from a python background lol

Anyhow, I'd agree with hotsuop in that Fabric is a good starting point, it's easier than Forge and provides tools to get you started.
Hopefully this helps :)

I would use Fabric template mod for getting the base of you mod but for editors i would use vs code or IntelliJ. but if your a real beginner i would check out Kaupenjoes modding playlists for learning how to mod

Good job! When it comes to software modding, finding the right tools is crucial. If you are into Minecraft modding like I am, you know how difficult it can be to choose the best software. I recently came across a blog post about capital asset software that is surprisingly relevant to our discussion. It offers insight into about fixed assets solutions which I think translates well to organizing modding resources. This can provide valuable perspective to our modding efforts.

MCreator might work.

Use blockbench, i use it for skins, and mods, also its free
