You''ll need to impliments some billboarding routine, then just map a sem-transparent texture where you want the crosshair to be. By semi-transparent I mean only one color (usually black) has an alpha of 0 and all other values are 1.

glOrtho(..)

Why not use :
glRasterPos2f(..);
//print Cross hair
glTranslatef(..);
//draw 3d world
This should work just fine...
glRasterPos2f(..);
//print Cross hair
glTranslatef(..);
