Hey could anyone help with this code please its LWJGL

[Josh1666]

Hey I'm trying to create a menu for my game so i have my three buttons (which are just rectangles at the moment) but i want to wrap text to them. however when i run my program a window just flashes up then immediately closes.I'm not entirely sure why it does this so I have posted the two relevant classes in hope you can help me :D thanks , josh
