	If you mean a VGA to 3xBNC for RGB cable, that is easy. You can build
one from Radio Shack parts in 5 minutes.
	However, life is not that simple, usually. Not many devices will take
VGA-style RGB signals. You need to say a lot more about what you want to do
with the VGA to BNC "adapter". If I recall correctly, VGA has separate V and
H sync. Most RGB inputs like composite sync. Then you need to worry about
timing. Are we talking RS-170 compatible ? Then you're out of luck. VGA at
640x480 I think can be compatible with 60Hz RGB.
	In any case, you need to give more details...
