best way to create UI java apps?

I've come across Netbeans but is there any tools out 开发者_StackOverflow中文版there that lets you build things event driven ?

I'm looking for a feature like being able to drag and drop UI components, and add methods to buttons directly by double clicking it (kinda like visualbasic) and viewing the source.

You can use Eclipse + Jigloo GUI Builder plugin.

In Netbean you have Matisse. See Designing a Swing GUI in NetBeans IDE

There's the Java Visual Editor.

This is nice if you're used to (or are considering using) Eclipse, which in itself is a very popular Java IDE.

IntelliJ IDEA features a nice GUI builder capable of using several layout managers. It's available in the open source community edition. I personally hate GUI builder and prefer more flexible solution like manually coding the layout with the all powerful and easy to use MiG Layout.
