you need a new strainer basket assembly, a dishwasher tee, bunch of elbows, compression/trap adapter (to fit the tailstock of strainer), some pipe, some ABS glue. Or you can try to see if you can find a whole kit that will fit (with dishwasher nipple) (see http://www.mobilehomerepair.com/kitchdrainkit.htm
Get a buddy that can do it for you if he has the supplies (like the glue and wrenches) and buy him a beer.
Or bring the photo with you to Rona or Homedepot and tell the guy what you want to do. Your is a little tricky because there is no pipe section that you cut on to of the tee to change the pipe, or you may have to change all pipes/fittings after the trap.
