graphic environment for testing

[moshi cochem]

Hi,
I just finished to develope a jar that knows to perform a few things.
To test the activities of that jar file , I was asked to make a kittle app
in graphic environment - like a little win form in microsoft, but in java.
In what java technology should I use ?
Thanks in advance.
