It would be nice to know how to do this using GIMP. Thanks.

You might try using the airbrush tool in "erase" mode.

I created the two tone background, then the black layer (with alpha) above it. Then I painted the arch using the paintbrush tool in erase mode stroking a path.

Then with the airbrush tool  also in erase mode, at roughly double the size of the original paintbrush, @ 90% opacity, stroked the same path. and got this:

Playing around with different values for opacity of the airbrush, allows you pretty fine control of how much "glow" you want.

You can also get some neat effects playing around with Filters --> Light and Shadows--> Supernova on the underlying two tone back ground (before doing the black overlay mask)if you desire a starburst effect
