Turbo Pascal also had an excellent object-oriented GUI framework for DOS called TechnoJock's Turbo Toolkit (later renamed to TechnoJock's Object Toolkit). I was able to build a full DOS GUI for my very first home-made database in a couple of hours. It was truly revolutionary for its time. I also used it to create the user interface for a BBS program I wrote with a friend. Still have all of it up and running on my DOS virtual machine.
