Sorry, but I think I can't help you, since I don't really understand,
what your problem is.

Perhaps you find help at http://gimp-savvy.com/BOOK/index.html
there go to "layer masks"

no, I am saying that when I applied the mask, the only way I can modify
Alpha values is using leves or curves, seleccting "Alpha" on the pop-up
menu and then modifying _only_ alpha values of the layer. But its a pain
in the ass doing it this way.

I am shure that there´s a better way ;) but you can try this:

- open the gray scale image, then Edit -> Copy
- open the working image, add a new layer with a layer mask,
  activate layer mask and do a Edit -> Paste in that layer
- in layers & channels, roght click on the layer mask and 
  choose "mask to selection" 

Ciao, Bjørn

In Corel Photopaint, one can load a selection from a gray
scale image. Is it possible to do that in GIMP?

Do an "Add Layer Mask". It's in the same menu with "Apply Layer Mask".
But it would be a plain mask, not the mask you've applied!!!

-"Layers"-"Alpha to selection" should be useful for you, too.

Also, have a look at the channels dialogue.

Hope it helps!
