How to create a Gantt Chart in Java?

Good Day to everyone. Can anyone be kind enough to give me an idea on how to create a Gantt chart using Java.
Your help will be deeply appreciated.
Thanks everyone!!!

If you were to code this from scratch you would probably need to create at least
30-40 classes (to keep it structured) and do a truckload of graphics and timelogics
coding. These guys want 400 dollars + to hand it to you, but if this is for professional
development I would advise you to go for the ready made solution.

Good Day. I appreciate a lot for your fast reply. Actually, i'm just a newbie in Java. I had been assigned to developed a customized scheduling system that utilizes a Gantt chart for a certain company. I had made a preliminary research about it, i come up with an idea of using a JTreeTables in swing and deploying it on the web with JSP.
It has the functionality of inserting,deleting,adding of rows and also drag & drop features.
Am i on the right track?
Thank you...

Your strategy sounds ok....
But, if this is work for a company then I assume that they pay you for this. No matter if
you have set a fixed price or not, you shoud try and estimate the time it will take
for you to come up with anything close to a third party (non-newbie) runtime version
of a gannt charting utility, and compare the cost and "elegance".

No disrespect, but If I was that company I know what I would have chosen.
