You should use maven to sort out what you need to download (really it 
will save you time)
- http://docs.codehaus.org/display/GEOTDOC/07+Meet+the+GeoTools+Library

At the bottom of that page it shows you want GeoTools jars you need to 
work with shapefiles. You can download the bin release and dump
them all into your IDK but maven hassle.

When you get there - here is how you can create a new DataStore file:
- http://docs.codehaus.org/display/GEOTDOC/04+How+to+Create+a+DataStore

Here is how you can create a FeatureType quickly.
- http://docs.codehaus.org/display/GEOTDOC/01+DataUtilities+Utility+Class

FeatureType has a create method that you can use to make new features:
- http://docs.codehaus.org/display/GEOTDOC/07+FeatureType

You can add those to a FeatureCollection:
- http://docs.codehaus.org/display/GEOTDOC/08+FeatureCollection

And then use a FeatureStore addFeatures method to write them out to your 
shapefile:
- http://docs.codehaus.org/display/GEOTDOC/07+FeatureStore

I would not mind using your use case as an example tutorial - but I am 
booked up today. Would you have time to join me on IRC tomorrow? If not 
just get on IRC and ask people questions.
Cheers,
Jody
