You haven't set the near and far clipping depths, so
they're defaulting to 0.0 and 1.0.

You need to call glOrtho() to set up a projection, e.g.

   glOrtho(0.0, screen_width, 0.0, screen_height, min_depth, max_depth)

where min_depth and max_depth are the range of z
coordinates that you intend to use.
