most 3d games have opengl set up for 3d rendering. when the menu is onscreen, you can use orthographic mode and translate the menu so that it is visible.

have you done this?

1.Push The current projection matrix. ( glPushMatrix() )
2.Call glOrtho( ... ) to set the projection matrix for orthographic projections.
3.Draw your menu
4.Pop the Ortho projection matrix ( glPOpMatrix() )
