yes, you could probably use something like your quest reward gump. You could set up pretty much any gump you wanted. The only thing the quest npc adds is the ability to launch gumps via dialog instead of something like doubleclicking a stone.

You might find the 3rd party progs like GumpStudio that can help design gumps useful.
There are explicit examples of quest gumps in the xmlspawner2 xmlquest/xmlquestgumps.cs script.

You dont need the gauntlet to test out the npcs since you can just set them up to be proximity/speech triggered. For the specific npc that I posted, just remove the NoTriggerOnCarried property assignment and then it will trigger whenever you interact with it.
