Arturius,
What types of apps are you talking about?
If you really need java and don't have any programming experience, I think either taking a class or getting some books will be required. O'Reilly is my favorite tech publisher, looks like they have a number of good options. Here are a couple:
http://www.oreilly.com/catalog/hfjava2/ - Head First Java
http://www.oreilly.com/catalog/learnjava3/ - Learning Java
O'Reilly books are generally geared towards a more technical audience, though Head First Java looks more like a general interest publication.
I'm sure there's a Java for Dummies book out there that might also be helpful.
If what you really need is to build simple web apps, then you might not need a full programming language and only need to learn JavaScript or PHP or some other scripting language. These are much, much easier to learn and I'm sure you could find web resources that would be sufficient to help you learn those.
