LiveCode GUI builder
The iOS (iPhone and iPad) version was released in December 2010. The first version to deploy to the Web was released in 2009. It is the most widely used HyperCard/HyperTalk clone, and the only one that runs on all major operating systems Wikipedia .
It might be possible to further simplify programming in LiveCode, by putting a narrower set of features up front, hiding many details. Simple action/response pairs could be provided without requiring any scripting. wikipedia site
Livecode started off as Metacard on Unix based platfroms before being ported to Windows and Apple based platforms in the late 1990's. It was a conscious attempt to reimplement HyperCard as a general purpose cross-platform authoring environment.
Like HyperCard, LiveCode allows you to build GUIs by dragging and dropping widgets, or drawing with simple line and shape tools. And it uses a scripting language similar to HyperTalk, but more powerful, with most of the capabilities expected from today's programming tools, such as networking and video.
