It is possible but not easy. You will need knowledge about writing Eclipse plugins and about Eclipse GEF. There are earlier entries in this forum that provide a little bit of info on how to do it. The main idea is that you have to look at the plugin.xml of the current GPD and mimic what is done for your own nodes. A good example to start is the ESB Service node implementation.
