Is a stout a 'difficult' beer to make?
Relative to other beers? no.
If you haven't made beer before, then all of it is difficult (well, depending on how anal-retentive you are). If you aren't concerned about infection or contamination, making beer is easy.

Sanitation, IME, is the hardest part about making beer.
Basically, you just put hot water (150-160F depending on what you're making) in a cooler that has a ball valve built into it (you can buy one from someone or make your own). Then you add your grain and let it 'steep' for a while - about an hour. Then you drain the liquid out of that into a boiling pot, boil that for a while (usually 60-90 minutes), adding hops at certain intervals specific to the style. Then you cool that down using a chiller, rack it into a fermenter, pitch the yeast, and let it ferment for a week or so. Then you rack it into bottles or a keg. That's about it.
As for books, Joy of Homebrewing is rather outdated.

We (husband & I) brew a lot and I drink more than my fair share of both homebrew and commercial suds. Definitely
don't get into homebrewing to save money on beer. That's like going into SLR photography to save money on film.
