That's gonna be really cool! I would reconsider your plant choices though... water wisteria, amazon swords, and java fern will probably be too big for a 3 gallon tank. You might want to consider smaller plants like various mosses, anubias nana petite, small-leaved stem plants, hydrocotyle, crypt parva, etc.
Also, is there a way for you to not run all the bulbs in that light fixture? 24 watts over a 3 gallon with no CO2 is a lot of light. I run 10 watts over my 2.5 gallon and I'm able to (slowly) grow many different plants, including stem plants.
