I'm new round here (just bought a new Mac with Mac OS 10.3.5). I want to build perl apps that can have things dropped on them and display alerts and file chooser dialogues.
Nobody's mentioned Pashua yet, which I found very interesting. It will give you dialogs with all the normal options, radio buttons, checkboxes, drop menus etc but it's not a full application-creating tool. http://www.bluem.net/downloads/pashua_en/
