Can I DIY undercabinet lighting in a house built in 2002?

I would like to know if I can DIY undercabinet lighting in our kitchen. We have only 3 or 4 spots that need lights. I'd prefer LED based upon coolness factor and I'd like it all on one switch. The upper cabinets go all the way to the ceiling and there is a lip on the bottom of the cabinets to hide the lights.
We live in the Boston area so outside walls are insulated.
Is this a project that I could tackle myself? If not, can someone recommend a reasonable price for the project?
