1. Most (but not all) experienced Java programmers believe that an IDE gets

in the way of learning the basics. Instead they suggest starting out with a text

editor and working from the command line to compile and run code. Old Skool rulez.

2. Some people have issues with the quality of code generated by drag'n'drop tools like the Matisse component in NetBeans. They prefer to write such code

by hand, or rewrite what such tools generate.

3. Have you programmed in another language before? Three weeks seems

awfully fast to be getting into Swing, but then I know those "Learn Java

in 21 Days" books get to GUI programming in week 2...

If you have Windows, right-click My Computer and select Properties. In that dialog is an "Apply" button that is disabled. If you right-click it, a "What's This" menu pops up. If disabled JButtons did not respond to mouse events, there would be no easy way for a Java program to implement something like that.
