Using the jQuery Mobile it is common to have two toolbars. The header and the footer. The seventh topic in my jQuery Mobile on going course covers the available possibilities when creating each one of them. You can download the slides of this topic and watch the video clips available below. I believe they will assist you with doing the first steps.
The professional version of my jQuery Mobile course is available at www.xperato.com. The community version is available for free personal and academic usage at www.abelski.com.
