Your code can be GPL and you can sell it, the only problem is that you can't prevent other people from selling it as well (or giving it away for free). Also you don't have to provide a free download to the general public. It's just that everyone to whom you distribute your code has the right to request the source code. You don't have to provide source code to people to whom you did not distribute the software. Of course anybody that you did distribute the software is free to put the source code up for public download. There are sites that do that type of thing, I've had GPL software I've written show up on download sites and such. But if you are maintaining your software then they will often be out of date and hopefully you'll be showing up ahead of those in search engine listings for your own products. Basically if you're providing good value, you're less likely to be affected by that type of thing.
