just make whatever commands into a shell script (type them into a text file and set its executable bit by doing chmod +x on it) give it a .command extension, set it to open in Terminal.app (get info on the file, and set it to to open in a specific application, specifically, Terminal)
You also have to add the path to the shell as the first line of the script. Something like:
#/bin/sh
or whatever shell you want. sh is usually best.
