There's no way that you have a computer with internet access but cannot afford a few dollars a month on a micro instance backend. My database for a big project is on the same machine as my web server which works fine. If you don't own a computer with internet, well you have my sympathy - that's tough.

I didn't say you must build a web product, but whatever you build must have a website.

Maybe English isn't your first language, or you're not trying very hard to understand the spirit of what I've written.
