Hi

I need to draw a two-dimensional Grid with OpenGL. I do not need any
3D-projection. So, how do I draw lines, and how to do it in 2D?

Thanks in advance

first of all if you only want 2D functionality, there may be 
better/easier ways to get it instead of OpenGL (eg SDL), but since you 
ask for OpenGL... just draw lines (GL_LINES), two vertices each of 
course. as for the projection... well if you don't want perspective then 
don't do perspective. set your projection matrix accordingly, or call 
glOrtho.
