You could spend a fortune doing all that and still come up with a mediocre or worse bonsai. Unless you plunk down the considerable cash for high-end lighting systems (no a single lamp probably isn't enough) you're not going to come anywhere near the high-intensity sunlight that "indoor" tropical species have in their native ranges. Consider what you're going to be paying to make a "perfect" environment for a $15-$40 tree...
There are plenty of people that can make pretty decent bonsai indoors, but they tend to be experienced bonsai people who understand the intricacies of what their trees require. Indoor bonsai is a very technical undertaking if you want decent trees.
As you might be able to tell, I am not an indoor bonsai person. I was when I began, but it took me about ten years to realize "outdoor" trees are easier, less finicky and more satisfying (and less expensive) than "indoor" bonsai.
It's worth noting that there are no "indoor" plants. Only plants that can tolerate being kept inside houses for any length of time. Bonsai in its countries of origins have never been kept inside...
RockM is spot on. In Wisconsin I grew tropicals indoors in the winter and got good results. But, I spent about $700 on the grow tent and lights, and that was only because I got a good deal on used lights.
