I want put a point in my citty map.
The point is my GPS location (latitudine, longitudine).
How I can put and draw a generic point with GeoTools?

For information on how to draw a point with geotools, see the tutorials
You will likely be interested in the "map and style" tutorial and likely
the "feature" and "datastore" tutorial.
The steps that you are likely to need are:
1) Read gps data
2) Create features for your points, with each feature having a point
geometry (or one feature with a multipoint geometry)
3) create a point style that makes a big dot (if you want a circle)
4) create a map and render your point features with your style
Alternately you could probably use the lower level renderer methods to
draw the geometries on your map. Also you could create multi-sided
roundish polygons to approximate your circle and then render them (as
Geotools does not yet have a datastore for gps data (see
http://jira.codehaus.org/browse/GEOT-104), but if we did you could use
it to read your gps data as features and reduce steps 1 and 2 to one
