Good luck keeping the basil from going to seed. You will need to have quite a bit of artificial light to prevent this. Even cutting them way back will not stop that very strong tendency of seeding, once daylength begins to shorten. Pepper plants would require a great deal of artificial lighting, as well, in order to remain productive during the winter.

I once kept a hot pepper plant in a south window all winter. It survived and produced a couple of peppers. It was only in a 8" pot, so if you use a larger pot and give it a sunny window or supplement with artificial light, it should work. The folks over in the hot pepper forum can give you advice on overwintering peppers. I've overwintered basil, too, but as Rhizo said, it needs lots of light. The leaves tend to get small and the plant will get leggy. You could try starting your basil from seed for the winter. I've never kept mint indoors, but what the heck, it's an experiment, right? Bring them in, and keep them in...I wouldn't be moving them in and out. Basil and peppers can't take frost, so bring the plants you want to overwinter in before frost. You can also check out the Growing Under Lights forum for more advice. Good luck!

What about moving the mint into a garage instead of your house? Chances are you will still have die back, but the chances are better of it coming back than if you left it outside. Keep it lightly watered and it should return.

I have 3, now 4-year old habaneros that I have brought in each fall to overwinter under my HD worklights (which are 500W). They grow a bit leggy under them (the lights are basically incadescents, meaning heavily at the red-end of the spectrum), but they bloom all winter and even produce habs during winter, because I also have a small fan blowing across the area that aids pollination.

My mother overwintered a genovese basil plant from last summer, under her 200W reading lamp and she recently planted it outside last month. LOL It seems to still be going too! I think it bloomed once but that didn't stop it from staying alive and continuing to grow. She also keeps an urn container of mints that she leaves out and it comes back each summer.

I think if I were to bring my mints in (my peppermint stays out in a wood trough through winter and pops up in spring, but I may bring in my pineapple mint), I might put that in a bright (but not overly so like the peppers) cooler spot with some humidity to let it have some dormancy - or at least, have it slow up a bit.

Peppers live to up tp 10 years and will live all that time in the Garden Pod. I use light closets I designed just for Perrenials. In the summer I use it for my bean garden and during the winter as a light closet. It's 2'x4'x6'. There are 3 levels and 3 sets of 2-4' flourescent lights. Each each of the three 2'x4' plywood shelves can be removed according to the height of the plants. You put 2-4' 6,000lum blubs with 2-warm kitchen bulbs and that bad boy will keep producing all winter. I kept 3 of these closets going on the back unheated porch and the heat from the bulbs alone kept it in the 80's when it was in the single diget numbers outside.
