Adding a button

Today a button was added to the Hello world app.  and with it going to a specific website.

I still don quite understand all of the java code behind it that makes it tick, but i have a good idea.

I think it would be a lot easier if I had a 2 screen set up, this way I could make the view much wider &  keep code that IS one line on one line
(ie not have 3 lines each w/ text relating to a piece of ode w/ the 3rd line having the semicolon that tells the program it is the end of that 'line')

But in any case as long as I have an idea why it does what it does & can duplicate it in the future I think I will be OK
