One way is:
Layer -> Transparency -> Alpha to selection  which selects the numbers and ticks. (If you do not want the ticks paint the selections out with quick mask)
Make a new transparent layer Layer -> New Layer
Choose the glow colour, depends on choice and eventual background, I used a neon blue-ish but a gold-yellow might work
Edit -> Stroke selection with a suitable size, for this small image 2 or 3 should work.#
Turn selection off Select -> None
Give the layer a small 2 or 3 Gaussian blur
Drop the blur layer under the dial
Merge down
Export as a png to save the transparency.

Most of that in a video https://i.imgur.com/GFg7lGE.mp4 might help

Thanks very much, that's excellent. They will show up, as they go on top of a darker blue layer. Thanks again. I tried adding the image to imgur, and although it goes through the motion, nothing seems to be there.
