Growing a Citrus Plant

I have always wanted to grow an indoor Citrus Plant, but have been nervous about starting the process. My apartment is covered in windows, but the large trees outside end up shading much of the warm morning sun...It drives me crazy that my home is not covered head to toe in lush green plants and I really need to figure out a way to make it happen... I wonder how well a simulated sun-light-bulb would work? 

This article on apartment therapy has great insight on growing indoor citrus plants and I may just have to take a chance, because having fresh oranges or lemons would brighten up any cloudy day!
