[Newbies] Porting BallonMorph to Processing (Java)

I really like the BallonMorph of Squeak (aka tooltip) and would like to port it to another programming language. But I’m a newbie in Smalltalk and Squeak so I’m having a hard time understanding e.g. the getVertices method. As far as I understand this method creates the vertices of the polygon that is the speech bubble?
It would really help me if someone could post this method in e.g. Java (my goal is to port BalloonMorph to Processing - see http://www.processing.org/) or give me some hints on how to read it.
Here is the method:
"Construct vertices for a balloon up and to left of anchor"
| corners |
corners := bounds corners atAll: #(1 4 3 2).
with: corners first + (0 - bounds width // 2 @ 0)
with: corners first + (0 - bounds width // 4 @ (bounds height // 2))) , corners
Thanks for helping,
