It's experiment time for me,lol

While out in the garden this morning I noticed I have 2 wild tomato plants, one is growing in the cooking onions the other is back by the cayenne's. I have a pot big enough to transplant them into, so I am wondering how long in the shade do I have to keep them until I can bring them in for winter time, or should i jsut keep them in the shade until it's almost frost time...
I want to do an indoor garden right on the kitchen table,lol. We seldom use it so I am thinking that is better than a cat lounge.....

What do you think? Doable?
