It's hard to learn to think in the language until you've seen it done 
several ways and then you've programmed it yourself over again.

I'm not sure what your program is going to do when it is finished but 
you can use the basic format that I gave to create lines or string lines 
together by following the mouse inputs.  You could add a popup menu to 
change color of the line or the style of the line as well.  The 
possibilities are unlimited once you've seen enough code to get an idea 
how to do it.
