How do I generate code with Matisse?

I am interested in building a netbeans module that allows me to use matisse to visually build a form, but instead of generating java code I want to build an XML file that describes the form, allowing construction of the form programatically from the xml.



I am also interested in building a module allowing use of the jgoodies FormLayout in matisse to java code as well as to the xml mentioned above.



So far, I haven't found any tutorials of things like this, or netbeans platform API's describing themselves as handling this, or source code examples of this i have access to.



Any pointers, tips, suggestions, or references would greatly help.
