Getting started programming in Java can be a daunting task. Experienced programmers don't think twice about creating a GUI and adding a JButton.

Scan the number of methods that are available to you from JButton directly and from the hierarchy from which it descends: AbstractButton, JComponent, Container, Component, and Object itself. All you want to do is create a button with a label that is tied to some action when it is clicked. What's all this other stuff?
That's part of the idea behind the Naked Objects framework. If you buy into the framework, you are supposed to be able to keep your attention on the business logic and allow the framework to help you with the routine but required tasks. Today's java.net featured article, Introduction To Naked Objects is a comprehensive introduction to the framework.

Brian Coyner takes you through a quick example of using the Naked Objects framework for easily providing direct access to business objects.
