Check out the Motorola MC1377P RGB-to-PAL/NTSC encoder chip.  It costs $2.95
from Jameco, and they will send data sheets for 50 cents.  There is a $30
minimum order, so you might try a local electronics store.  The 1377P will do
what you want with little additional parts (resistors, caps, colorburst crystal
or TTL clock signal).
