It all depends which widgets you use for the layout; FlowPanel for
example is a simple <div>...

Several solutions:
- don't build your form with GWT and instead wrap GWT widgets around
existing HTML elements:
TextBox myBox = TextBox.wrap(Document.get().getElementById("my-
box"));
i.e. use progressive enhancement as you were used to with jQuery.
And if you want a jQuery-like approach to get elements, have a look a
GQuery: http://code.google.com/p/gwtquery/
(beware: you cannot wrap nested elements; well, actually, you can,
at your own risks; either disable assertions in hosted mode and/or see
issue 3528)
- use an HTMLPanel with placeholders where you'll inject your GWT
widgets (there's no HTMLPanel.wrap() but it could be somehow
simulated:
RootPanel rootPanel = RootPanel.get("thingToWrap");
HTMLPanel panel = new HTMLPanel(rootPanel.getElement
().getInnerHTML());
rootPanel.getElement().setInnerHTML(null);
rootPanel.add(panel);
it'll add a <div> –or whatever "ag" you passed as the second
argument to HTMLPanel's ctor– in between the "root panel" element and
its children as they appeared originally in the HTML code)
- use UiBinder that'll ship in the upcoming GWT 2.0
I'd personally favor UiBinder if possible.
