Any download that allows random B/W stone placement?

Greetings,

I need a basic download API that will display a board and stones. I also need to select black and white stones without alternating the color. (So I might place 4 black stones and the 5 white anywhere on the board.)

A nice GUI that displays the bowls and the board would be great!

This is not for game assessment but for showing basic patterns and stone relationships.

I’m sure there is a free API oout there but I just don’t know where to look. Any help?
