Well ultimately any new endeavor is going to be scary, but if you want a wortwhile job done at anything, you need to brave the storm and go at it.
You can do what you wish, as it's your cab, but coming into a place names "Build Your Own Arcade Controls" and asking about a pre-made construct will get you a majority of answers fitting the name of the place. (that and the X-arcade line doesn't really have the utmost of respect around here)
Wires, wood, and tools aren't really all that scary. Like anything in life, it's key that you be educated and do things right, and that's what the majority of us are here for, as a community.
If anything, maybe the CP by itself is the best way to weather the storm and help you build confidence, as it's a smaller construct, not very risky weight-wise, and mostly everything is re-usable..
If you wanted to make your own cake, but you didn't want to bake because you're scared of flour and heat, you could just buy a cake, but the satisfaction that comes with eating a great cake you baked yourself would definitely outlive any pre-purchased cake.. that and the knowledge you gain will help you with other endeavors, like...pies.
