The implementation is in 
modules\unsupported\gpx\src\main\java\org\geotools\data\gpx\temporal

I've created a TemporalCoordinate class, which extends the JTS 
Coordinate, and adds a 4. ordinate. I've also implemented the 
TemporalCoordinateSequence and TemporalCoordinateSequenceFactory classes.

The problem was mainly in the referencing module, as that couldn't 
really transform between 2d and not 2d CRS-es, that would have been 
needed for uDig. Finally we concluded, that there is no "easy" solution...

I'm still interested in a general solution though :)
