[LWJGL] I'm VBO'ing wrong...

Hi! My problem is hopefully pretty straightforward. I’m starting to move away from immediate mode rendering and getting my feet wet with VBO’s! I’ve seen a couple of tutorials, but when I try to write it out myself, it just won’t render. I’m trying to render this 64x64 texture I made, which works fine in immediate mode, but when I try to use a VBO, nothing renders.

Here it is: http://pastebin.com/mc4yvdvK

Any idea why it doesn’t render? (like I said, immediate mode works just fine)
