Photo Light painting within Gimp

Hi All, I am looking for Tips/Help regarding Gimp navigation/layers. I have recently migrated from Windows to Linux as my preferred OS. I had been using the Adobe LR PS for my photo editing within the windows environment an option that is now unavailable to me in Linux.
I am looking to duplicate a technique I used in LR where I stacked photos as layers they could then be blended by using a brush I could expose the lower image (or part of) in my stack. The stacked photos are all of the same composition (night photography) but several photos were taken using a long exposure. Where some exposures I had performed some light painting to an object in the foreground. Hope that makes sense?
Can this technique be performed or duplicated with Gimp?

That sounds like a Layer Mask.

Thanks Blighty, think you cracked it. layer mask looks promising. figure I can play with that and duplicate the technique I have used with LR.

As Blighty mentioned, masking. An example in gimp:
