Princerr5

I don't like installers, It really bugs me if i don't know what they do at all. I've done some research and apparently I need some "libraries" Does anyone know where to get those?

I was trying to download forge manually, because I don't like using installers. I am using forge version 1.8-11.14.4.1563. I created a new folder called 1.8-Forge, extracted version.json, renamed it to 1.8-Forge, basically everything I needed to do. After all of this, Minecraft won't launch. Launcher Log:
