Shell Script Launcher

I'm looking for a MacOS X GUI utility to facilitate the launching of shell scripts. Ideally, I'd like to have something running in the menu bar, whose contents reflect a listing of the shell scripts (sh, bash, php, etc.) that I have stored in a particular folder. Selecting an item from the menu would switch to Terminal and execute the shell script in a new window.

That's the basic requirements. Getting fancy -- it would be nice to be able to drag-n-drop a number of files on any script name in the menu, and have those files passed as command-line arguments to the script.

Anybody know if such a utility exist?
