Thank you for the links.  
The serial part I understand. The examples are pretty clear.  
What I am looking for is how to create a user facing form/dialog in Processing to let the user type in numbers or select from a list. If I have the data from the user, I know how to get the data to/from the Arduino.  
So, the front end options/examples are what I need.  
E.G.,

- How to present text?
- how to capture text from the user?
- how does the user select from a list?
