I would use phantom''s idea, but instead of enable blending, set up the alpha test to remove any fragments with alpha 0. The alpha test is done on a per-fragment basis, earlier in the pipeline, so it''s quicker.

glBegin(GL_QUADS);
  glVertex2d(0,0);
  glVertex2d(width,0);
  glVertex2d(width,height);
  glVertex2d(0,height);
glEnd();

frankly i dont see what's so difficult.
perhaps you should read some basic OpenGL tutorials.
