There are quite a few websites for hosting webcomics but the issue is that AFAIK all of them banned AI related stuff whether it be because artists dislike it or them being seen as low effort spam. That's going to be the hardest part of convincing others to give your comic a shot.

For programs I suggest Krita, professional artists use it and it even comes with comic templates to get you started with panels.

I started with stick comics. XKCD still draws stick comics. If the story is compelling, people can get invested in your creation. If you want to do action sequences, etc. do 'em with a sense of humour (and stick people) and the right audience will be on board.

There is a hard limit on the amount you can upload and such, but you can create a Neocities site.

Only thing you need is a working email, a username, and to know a little bit of HTML/CSS/possibly Java (which is optional unless you don't want a static site).

It has a free tier, but since storage for your site is limited, it might not be the best long term solution. It's also not if you decide to pay the $5 monthly tier for more storage since once you run out of storage on either plan, you cannot upload more files (except if you go from the free tier to the $5 tier).

Also, the $5 tier might be more since I have not checked in a while since I just use the free tier for a static site.

Tildes offer free website hosting along with many other services. As long as you can use a terminal you are golden. Check out tilde.team or tildeverse.org

Practice drawing. Get an artist’s anatomy book and practice. Pick something you see every day and draw it every day. If you have an idea for a comic, write and draw it. You will get better with practice. Start with pencil and paper, an art app will be much more useful if you already have the drawing chops.

Don’t use AI art because that just recycles other people’s art without crediting them or paying them.

I hope you can get the help from Parker Publishers they are quite good in COMIC. you should check this.
