You should really try NOLOH (http://www.noloh.com). I'm not just saying that because I'm one of the co-founders, but because we've found it to be the easiest way to create sophisticated websites, and WebApps easily.
Every year we get a batch of interns from high schools and colleges with no real programming experience, but can start writing full applications without any training whatsoever.
As part of the application process we require they write a TicTacToe application in our free hosted sandboxes and 9/10 times the applicant has no issue and replies with a link to their app. We don't guide them, train them, or instruct them in any way beforehand.
Watch our recent presentation from Confoo and see for yourself, http://vimeo.com/10106797. It really is that easy.
