Here's an example of a typical small scale DWC rig:

If you have any imagination, you can visualize how to build the rig yourself. I've built a lot of good units out of all kinds of containers that were headed for the landfill. These things are about as low-maintenance as can be. I encourage you to try the method out. If you have anything resembling a green thumb, it is easier than growing in soil.
Here's another compact design that is awesome for starting seeds and rooting cuttings:
These little units can be built to house miracle growable seed pods for a transplantable, organic container. DIY seed pods can be fashioned out of locally sourced materials. Once some healthy roots poke out, the clock starts ticking before the container explodes. Be aware that most "potting mix/seed starter mix" media holds too much moisture and must be cut with perlite or other bulking agent.
