Question

"Reference Implementation" for people (like me) how want to develop a modular, extensible, application on NetBeans Platform.

Link to VisualVM project

(Like Stock Trader is a reference implementation for Microsoft Prisme)

Answer 1

If you want a reference Implementation then the NetBeans IDE is about your best bet.

Another project that would be very worth looking at is BlueMarine, It's been around for a couple of years now and Fabrizio Giudici has really worked hard to make the project look different from the IDE.

EDITED TO ADD There isn't an official Reference implementation in the manner that you speak of, and there has been discussion recently about adding more complex NetBeans platform samples. See here and here

Answer 2

There are lots of open source NetBeans Platform applications to look at: http://platform.netbeans.org/screenshots.html
