I want to have a mouse cursor replacer in OpenGL, located at Z=0 -- however, I have no clue how to do this. I know how to retrieve the mouse X and Y positions, but how can I place a crosshair image onto the cursor position, regardless of the camera position?

Change the projection matrix to 2D orthographic projection, which allows you to render 2D objects on the screen regardless of where the camera is.
