Yes.

No.

You may have misunderstood me - I was suggesting that if you wanted to
have multiple OpenGL contexts in multiple overlapping regions of the
screen, you could arrange it like so:

GtkWindow
  GtkFixed
    GtkDrawingArea 1
    GtkDrawingArea 2

If, on the other hand, you just want multiple windows:

GtkWindow 1
  GtkDrawingArea 1

GtkWindow 2
  GtkDrawingArea 2
