Well I think I got what I was looking to do. I'm not sure if it is the easiest solution or not but seems to work.

I create the rounded rectangle as desired in a new layer. I select the entire rounded rectangle and shrink the selection by 10 pixels. Next I border the selection by 6 pixels and create a 2nd layer to fill the bordered part with the desired color. I end up with a 2 new layers - 1  that has the 50% transparent black region and 1 that has the halo glow.

how to do this?

I can create the rounded rectangle and fill it with black and then reduce 
the transparency to 50%. So far so good. The problem is the halo affect. 
Please help me out.

are you trying to use selections?

the Simple Floating Logo tutorial at www.gimp.org tells indirectly how
to get this same effect.  it is an old tutorial, originally written for
gimp-1.0, so things work a little differently now -- but not that

if you are able to get the shape you want in a selection, transform the
selection into a path and use the Stroke Path dialog to make the white
on black part for the tutorial.  after that, use the tutorial as if your
shape is text.  you might need to fiddle with the settings to get the
right sort of transparency for the tubular look i see there.

selections are actually layer masks -- and if you watch the Channel
Dialog while working with them, you will see that.

i have found that simple jobs are done very nicely with Selections but
if you really would like to have control over your efforts,
understanding how layers can and do work is the very best way to handle
and work with GIMP.

let me and the mail list know if you are successful and which method
worked best for you!  everyone has different experiences and successes
and i am curious about all of them.

actually, not getting it to work is just as interesting to me....
