How can I design User Preferences module in my Swing application?

I have dialog for storing user preferences of the application which is developed using Java Swing. There are 20+ preferences and I would like to notify other modules when the particular preference changes. I know that I can hold a list of listeners and notify them whenever the preferences change. However, I would like to know about two issues:

• How can I bind my Swing components to a bean object,
• How can I fire an event when the preferences change,

Dependending your experience, how would you resolve that architecture? What are the best practices to follow?

Thanks
