Yes, it's very possible. It's also quite difficult. If you have an economical support system, you should be able to make it work, but if it's something you have to do before date X, it might be a problem, both since everyone learns at a different pace, and because quite honestly you might find out that it's not for you.
I would suggest Javascript for a beginner. Start at the front-end, that's an area where there is tons of work being done, tons of new work created all the time, and (last but not least) tons of tutorials and free courses available.
After that, you can (if you want to) work on a back-end language, but I would suggest trying to find paying work in the front-end first. Many jobs require full stack experience (front and back-end), but being good at front-end development should be good enough for tons of jobs. Then, when you've got a few paying jobs behind you and want to expand your job opportunities, you can select a back-end language. Which is up to you, and you'll be much better able to make that decision when you come to it.
You COULD actually become a very experienced full stack developer without spending a penny on anything but your computer and power and internet bills. But there are also tons of resources that are very valuable and worth what they cost. You'll decide which those are as you go along. Pro tip: try before you buy.
Finally: The good news is that working from home is very common in the business, the bad news is that many people will require weekly/monthly or even just random face-to-face meetings/group sessions and stuff like that. Honestly, if travelling isn't too much of a bother for you, that shouldn't be a problem for you depending on your disability. It's either one of those "remember we're all in this together" things, or a "let's get everyone in a room so we know everyone is on the same page" things. That's usually quite social, and generally considered a good thing. You could also manage to just work from home, but chances are you will find that that excludes you from a lot of good work, and there are some really nice people in this business that you could really benefit from meeting and talking to face to face, even if you have a disability. IT is an extremely inclusive field, and I think you'll be surprised how little disabilities matter when you're deep into a discussion about which framework is the best representation of MVC, or which state library is "best". :)
