A Full New Crafting System

Hello everyone!

I'm here for the first time, sorry for any English mistake (isn't my default language).

So I want to ask if is someone knows a way to crate a full new crafting system. In overall, GUI and Block are easy, procedures too.

I've been looking this for some weeks, but i didn't found anything that anwser my primary question:

How to create a new crafting system that its recipes can be found on NEI (or too many itens). Ive thinked to created a New Java Class within the methods need. Like Registering the recipe and "drawing" it (Something easily than traditional recipe method). The method failed, obviously. I mind my error was on registering, because i don't know how to use the Forge Register method correctly.

(I don't have anymore the code ;--;)

If someone knows something that may help, i'll be greatfull.
