WindowScript was designed to create your own complex dialogs with
window controls. You could call them from within your HyperCard stacks
and add scripting actions to them. In combination with [Double-XX][1]
and [CompileIt!][2], also distributed by Heizer Software, it provided
a decent standalone application development environment.

(v1.5.2a)

Compatibility
Architecture: 68k

Requires HyperCard.
