title: Creating buttons and icons in OpenGL
body: <p>I'm trying to make an editor using OpenGL similar to MS Paint, with a panel and all. Where can I find material on how to create buttons and icons?</p>
  
  <p>P.S - I did find out about GLUI that provides such entities, but I am not allowed to use anything other than GLUT.</p>
  
  <p>Source code, if provided, will be very helpful..</p>
