Why would you bother with etching such PCB yourself if you can order 10 of them for $4, and that's including shipping? Get two sets of components in case you screw up and then just solder all this
exclusively through-hole and one-sided stuff with cheapest iron around.
The hardest part will be ordering the components, or more specifically verifying that you got them right, as the KiCad project does not include a BOM. Other than that, it's as easy as it gets. Entry-level workshop stuff, about as complex as ArduTouch. People who never held a soldering iron in their life successfully learn on this kind of boards.
(and if you're willing to spare a few more bucks you could even get it assembled by a PCB fab and just receive ready-made boards in your mailbox - the prices aren't prohibitive there either)
