Glad you enjoyed it ! We also enjoy working on it.
Unfortunately we don't have a Netbeans plugin for Forge. There is some work being done in the IDEA plugin, but nothing official atm.
Would you like to give it a try ? You can join us on irc on #forge if you feel like it.
About the tutorial on the CRUD app, that would require writing a new scaffold, like described in http://forge.jboss.org/docs/important_plugins/ui-scaffolding.html#content
Hope it helps !!
