Odds are you'll never have enough time to learn programming at the depth that someone who is very good at it knows it.
Start small. Learn how to write a static web page using nothing but Notepad in Windows. Then, when you've mastered that, try using CSS to change the way it looks.
Then, write a simple "desktop" calculator as a web page.
This will likely take you a few months or weeks if you spend a lot of time at it. Remember, use Notepad only. Don't worry about making it work in anything but Internet Explorer (or your browser of choice) because that will make you insane.
When you can write Tetris, then you're ready to work with databases and servers.
Don't use MySQL, it's an abomination. If you have Microsoft Access, start with that. Make a project in that that real people will use. If maintaining it becomes difficult, it's because you don't know enough database theory. Figure out on your own why you want data to be fully normalized and only flattened with many saved SELECT queries. Try to figure out how to write the queries in SQL using the (excellent) query editor. Write UNION queries.
Now you're ready for a server and web site.
