I just bought a Sharp CZ-612D monitor for my X68000 Compact, however it did not come with a cable to connect the two. Does anyone know where to buy such a cable?

I don't know anywhere outside of japan that'd have reason to sell a male-male DB15 cable. You can order one from there, through the usual places, but it'll be quicker to build your own.
It's just a straight-through cable, the pinouts are right here (http://www.gamesx.com/wiki/doku.php?id=av:japanese_rgb-15). Start with a 15-pin extension lead and cut off the female end, replacing it with a DB15, or even a VGA cable and replace both ends.
I guess this one will work then, although it only says "NEC PC-9821/9801":
