I came across a neat little tool for Mac OS X called Platypus which turns scripts into applications.
From the web site:
Platypus is a developer tool for the Mac OS X operating system. It can be used to create native, flawlessly integrated Mac OS X applications from interpreted scripts such as shell scripts or Perl and Python programs. This is done by wrapping the script in an application bundle directory structure along with an executable binary that runs the script. Platypus thus makes it possible for you to share your scripts and programs with those unfamiliar with the command line interface, without any knowledge of the Mac OS X APIs — a few clicks and you will have your own Mac OS X graphical program. Creating installers, maintenance applications, login items, launchers, automations and droplets is very easy using Platypus.
A nice alternative to running scripts off the command line.
