I'm new with the OpenGL code and I wanted to learn how to make a simple terrain, more of a chunk of blocks.
I want to use SimplexNoise for this, and it's pretty difficult for me to understand how to do it.

I divided my files, to a main file that will render and "draw" all the blocks, and a chunk file, to create every chunk for itself.
If you can help me understand better what I need to do, I'll appreciate it.

Files? Do you mean threads?

As for the explanation, I recommend checking out the JGO forum. It's a complex and diverse topic and there are a a good number of excellent topics on JGO. Sorry I couldn't be of more help but I think I'm being of more help pointing you there.
