Platypus

There is a bug in Platypus 4.2, where dropped files won't be passed as arguments to the script. For this functionality, you'll need to revert back to Platypus 4.0 for now, until I get this fixed in the upcoming 4.3 release. Platypus icon

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.

Executing scripts with root privileges via Apple's Security Framework

Development

For help with development, you can subscribe Platypus Developer Mailing List and send in your query, or maybe give the documentation a once-over again. If you like Platypus, you may also be interested in a similar application of mine, Tapir, which allows you to easily make global Mac OS X menu items based on shell commands and scripts.
