Going from VGA to composite without an adapter containing the appropriate chips is not possible. Going from VGA to component is possibly doable. You can see the VGA pin out here. As you can see there are rgb outputs and rgb grounds. But there are also horiz. sync and vert sync. I don't know at this time what you would do with these. I suspect that going from vga to component also requires some "magic chips" that will translate the one to the other. I also did not research signal levels. There is a possibility that the signal levels from the computer will not be high enough to make the display device display.
