Hi Aaron,
If all you want is a simple dynamic UI there's no need to
overcomplicate things... below is a self-contained, executable Swing
example of arbitrarily placing some components on a form. Of course
some people might say that anything Swing is overcomplicated, but I'm
a fan so what the heck. This example may not demonstrate best
practices in Swing, but if it's results you're after then this may be
right up your alley. (Please disregard the JFormDesigner stuff...
that's just me cheating.)

Could you elaborate on what you mean by "drawing the screen
dynamically"?
I get an XML feed from the server and it will have something like the
following:
<form id="form1">
<button id="btnSubmit" x="12" y="100" value="Submit" />
</form>
Based on that I know I need to display a form with a single button
on the
screen which I do by parsing the XML and incrementally "drawing it"
by
instantiating AWT objects and adding them to a panel/frame.
The snippet looks very close to something HTML'ish, so perhaps you
could
use an XSLT-stylesheet to create HTML you could use in a web page?
The
logic for that is very simple.
It all depends on how much functionality and speed you need.
