This maybe a very simple question but I appreicate your answers.
How can I display the 'fieldDescription' on top of a field widget, not below the field?
You might need to overlay respective field component & make a adjustment. Ex:- For text component overlay  & at text.jsp comment out  & place  at desired location you need.
LayoutHelper.printDescription(FormsHelper.getDescription(resource, ""), out);
