For those that like HyperCard, I really recommend looking at LiveCode (www.livecode.com), it is a modern version of it that is able to generate standalone applications for MacOS X, Windows, Linux, Android, iOS and the Web.
They have a FOSS version behind that confusing website, the livecode.org site has access to the GPL version, you can download without acquiring a membership. It is just a bit hidden.
