Smalltalk and Squeak - Squeak is a full environment built only using Smalltalk language. Smalltalk has very simple syntax but at same time is very powerful and compact. Squeak contains all the development tools you need as well as some other applications and games. It runs on top of most OS'es. Using Squeak is the easiest way to start developing in Smalltalk which all should try at least once. Smalltalk was invented by Alan Kay and it was designed so that his 5 year old son should be able to develop programs using it. Also check out DabbleDB developed in Seaside.
