While a sunny window may suffice for some plants for a short time, you'll generally get better, more consistent results if you use artificial lighting, either alone or to supplement window light. The type of set-up you choose is really a matter of cost and convenience. What is most important is the quality and intensity of the light. Quality. Use only regular fluorescent lights or special plant "grow lights." Incandescent light bulbs can get too hot and burn tender plant tissues. Intensity. Remember this fact: Light intensity diminishes as you get further from the light source. Arrange your lighting system so you can keep your plants as close as possible to the light source (without touching it). You'll need to be able to adjust the height of the lights as the seedlings grow.
You can rig up a homemade seed-starting set-up using shop lights and shelving. However, prefabricated seed-starting light carts are designed for this purpose, with adjustable lights, waterproof trays, and other convenient features. Since you will be working around electricity and water, be sure your system is grounded. Use 3-prong fixtures, and keep water away from the lights, extension cords, and fixtures.
