creating ui elements with java for max for live

Hello.

I want to have a canvas and to be able to draw on it and to fetch mouse events on that canvas.

I read on the net that I can use swing to create UI elements but it will be separated from the main window. can I use any other GUI libraries in order to create a new user interface item in that window ?

does max comes with a canvas component that I can use to draw on and fetch events from ?

any information would be greatly appreciated.

thanks!
