Exactly what I was looking for.
For everyone else that wanted to do this here is an example.
Go to
http://www.google.com/webfonts# pick your font you like and to the right click the add to collection (blue button).
Then at the bottom click use.
Towards the bottom you will see integrate the fonts into your CSS.
IE font-family: 'Merriweather Sans', sans-serif;
You take the
$googleFonts['FontName'] = 'FontName';
and add it into the correct location of the list on a new line under (../templates/j51_yourtemplate/elements/googlefonts.php).
When you have
$googleFonts['FontName'] = 'FontName';
pasted to the file you will need to add the Merriweather Sans like this
$googleFonts['Merriweather Sans, sans-serif'] = 'Merriweather Sans';
Hope this helps everyone else.
