You can go to the following link to the sun page for JavaTM 2 SDK, Standard Edition Documentation, click on the download page and get all the classes including the AWT.
Download to your harddrive, set you path and classpath, and you are in business.
http://java.sun.com/j2se/1.3/docs/index.html You might want to be aware the the new swing components are (slowly) replacing the AWT because the AWT components are "heavyweight" (they have peer components on the operating system side) and the swing components available in the 1.2 release are "lightweight" components (they are completely separated from the operating system).
In addition to using less system resources, the swing components look alike on any operating system while the AWT component pick up the look and feel of the underlying operating system (i.e. a button on windows will look like a windows button. They same button on motif will look different - more like a motif button).
