library to create basic UI for OpenGL??

Can anyone recommend a library for Unity to create basic UI for OpenGL that does buttons, list boxes, drop down etc… and also does basic mouse hit testing?

not sure why this is on a unity board, but check out GLUT

http://www.opengl.org/resources/libraries/glut/

There is a bunch of libraries. Start by browsing the GUI @ Asset Store to skip vaporwares…

Great, thanks everyone.
