Hello!
You have reached an area where the GeoTools library needs work; what
you need to output your file as GML - is the "XSD" file matching your
SimpleFeatureType. The wiki page provides an example that you can
modify; but right now we do not have any code that does this for you.
Once you have an XSD file the encode file will be able to help you.
The idea of a "GML" file does not exist; it is simply a convention
used when defining your own XML file. When you define your own (using
the ideas in GML) you will have an XSD file describing your file
format; which GeoTools can then encode against.
