Java applet for Tower of Hanoi

I am planning to write a Java applet for Tower 开发者_开发百科of Hanoi similar to link( http://www.mazeworks.com/hanoi/index.htm ) Can you suggest how should I start and proceed.

And, btw, does it require multi threading?

And also, major part of my doubt is

• detect a tower (if a disc is being dragged using mouse)

I would start with this http://www.rstack.com/hanoi/hanoi_src.html or http://stud1.tuwien.ac.at/~e9125168/javaa/jtower.html. As far as threading see my comment on Jonathan M Davis's answer.
