1. Create new transparent layer, select it, leaving background visible.2. Make rectangular selection to leave the border width desired (say 50 pixels) and invert ctrl+I 3. (optional) Select-feather choosing width half border width (say 25 pixels) 4. Select foreground color desired and drag to image. (will leave a solid (optionally feathered) border)
5. Drag opacity slider to 50% or to taste. 6. If "happy" merge visible.

(The layer will become transparent, but the original color data is still there.) * Choose your paint tool and set the Opacity slider (in the Tool Options) to the level of _transparency_ which you desire. If you want the border to end up with 20% opacity then set the slider to 80% (fifty percent opacity means fifty percent transparency). * Paint the duplicate layer. (You can toggle the visibility of the original layer to see how the semi-transparent result of your painting will appear; however, the unpainted regions will not be visible.) * Add a layermask to the duplicate initialized to "Transfer the layer's alpha channel" with the "Invert" box checked.* Hide or delete your original layer.
