If you can handle loading 4x5 film holders, developing your own B&W film is a piece of cake. I *would* recommend learning with 35 mm or 120, if only because it'll be easier to find equipment designed specifically for those formats and you can very easily find folks who already do those and can help -- OTOH, for $4 you can get food storage containers that will serve nicely as 4x5 trays (or, for about $15 including shipping, you can get a set of real plastic 5x7 trays from U S Plastics); weatherstrip to light seal a bathroom door will cost about another $6, and I made the shield I slip into my bathroom window from a full sheet of black-core foamcore board, some strips of black matt board, and some black masking tape, for a total outlay of about $11. Kitchen measuring cups (suitably marked, of course, to ensure they don't wind up getting used to measure milk or salad oil after they've been used for developer and fixer) make quite passable graduates, and I store my mixed developers in old pickle jars and water bottles (again, suitably marked, and there are never children in my house).
For whatever it's worth, I learned to develop film at summer camp, at age 9, and did my first unsupervised roll the next summer -- from mixing the developer, stop bath, and fixer (Kodak Tri-Chem Packs were discontinued, but I got some at a yard sale along with the developing tank), to improvising a dark enough area to load the film, to processing, leaving me with a roll of beautiful 620 negatives that I then had no way to print, store, or (in 1970) scan... Developing is *so* easy, it's tempting to suggest it's worth learning that before you worry too much about exposure and focus...
