I really like Processing . Processing is a Visual Programming language, and it is based on Java. It is designed to run either as an Applet, a Standalone App, or as a Java Component; running a Processing Sketch as a Component is the one with less documentation, but probably one of the most interesting and powerful applications of it. This is a small guide on setting up a Processing Sketch as a Java component, ready to use on your Swing or AWT desktop applications. I am assuming you have a basic notion of Object Oriented Programming, and preferably a base on Java, as it is obvious, you will need basic Processing skills.
