No need to create any new widget areas.
Just tested my approach and it seems to work for me.
I've set up 3 Footer Text Widgets (Left-Center-Right)
Added some <p> text to each and styled it.
Edited the center footer and added
<h4>Let this stretch over the whole footer please! *****************************************************************************************</h4>
Repositioned it using:
footer#footer h4 {
position:relative;
top: 60px;
left: -100%;
}
You'll need to make adjustments to suit yourself.
