Oh yeah, sure my friend. You're going to implement

  * text entry (right to left as well as left to right)
  * file browser
  * treeviews that scale to 50k nodes or 10x that
  * menus

in GL in a month. Not believable.

Never did they ever say that would implement the UI of Blender (I assume that's what you were referring to) using OpenGL. I think what they meant was that implementing just a UI in OpenGL isn't as hard as the other guy thought
