Yup!
That is exactly what I ended up doing.
I wrote my very fist shell script and then put it into an AppleScript which I can then launch as an app.
Actually, the shell script would have been fine on its own, except that it always left an open terminal window behind and I couldn't figure out how to prevent that.
But, calling the shell script from AppleScript with the 'do shell script' command seems to avoid the terminal window.
I'm sure there are much more elegant ways of writing the commands, but it does seem to work...
