1. The former Sun website is a good starting point: http://java.sun.com/javase/technologies/desktop/
2. Take a look at embeddable databases like H2 and HSQL
3. I second @Napul here: Netbeans has a decent GUI builder

First you would want to pick how you want to build your UI. You can use swing, but this seems to be a fairly large list of alternatives ways to building your UI. There are a lot of other tools out there, I haven't looked that much though, I tend to prefer to just use Swing.

For small dbs you can use SQLite. This works very well. I have also used memcached but, the data was only needed for the duration of the application.
