how can I make this pendant light?

I need a creative lighting solution to replace an old fixture with a pull chain, there is no switch in the wall to turn it on and off. I would like to safely build a light similar to the ones pictured.  I have rewired lamps in the past and this seems like it might be a similar project, but with a few adjustments like strain relief components as well.

I have found several companies that sell keyed sockets with uno threads to attatch shade holders. There are also great reproduction cloth covered wires available. I have 2 great glass 2 1/4" shades I would love to use.

If its possible to make 2 lights that can be operated by a key in their sockets so that the can be turned on and off individually, but wired together, and run through the same canopy and connected to the same box that would be ideal.
Can anyone help me with this?
