ABSTRACT
In Photoshop, you can create your own dialogs using scripting. When you build a custom panel using Configurator, you drag and drop the controls onto the panel and then fill in some values for certain properties. Maybe you write a script to fill out the functionality. Configurator is a visual editor for building panels. To build a custom dialog, you have to do everything in code. The good news is that many things are already done for you. The ScriptUI classes handle a lot, but you still have to put it all together.
