Direcly I can't think of a way. The easiest way, and the way I would do it if I had to, would be to use a modern receiver with hdmi inputs. Plug your pc via hdmi into the receiver and from there send the signal to the tv with whatever output works for you. Otherwise you are going to have to buy a hdmi to composite adapter that costs at least 50 eggs.
The cheapest thing you could try, is buy a vga to composite/cinch/svideo cable, 2-3 eggs, and use a 3.5 to cinch cable to transmit audio. Be warned though the analog TV resolution is going to be around 640x480, so its going to look like ass. I tried it a few years back and just ended up buying an HD TV instead.
