Always nice to read about NetBeans Platform work in Holland, since I live there and it shouldn't be hard to set up a NetBeans Platform course there. Here's Glotaran, a biophysics (spetroscopy/microscopy) application from the Vrije Universiteit in Amsterdam, would be cool to do a course there.
Interested in a NetBeans Platform course, as outlined here? Free for universities, colleges, schools, and non-profits. Drop me a line or leave a message here if interested.
