So basically I have covered all the basics in mod creation, and I wanted to start adding gui's to my 1.8 mod, and I found a tutorial, however it doesn't work, can anyone give me some advice and/or link me to a good tutorial that works?

 

~Thanks in advance

If you want direct answer: Guis didn't change much since 1.6. All tutorials are close-to-good.

Note: I am not talking about containers, those changed much.

 

As to how-to:

Best teacher is vanilla itself.

For simple Guis (opened by some trigger like keyboard) you can use GuiScreen as base.

You simply extend it and open with player.openGui or mc.displayScreen (something like that).

 

EDIT

Before you ask again for tut links: There are not many good tutorials for Guis. There is one simple reason - Gui is a very mod-specific thing.

Post wat are you planning on adding and we can help more (a lot more).
