Yes, Cocoon can do all this (and a lot more)! If I were you I would take a closer look at XForms, the will provide you with extensive form-handling capabilities, including complex validation support. For the database part, you can use either XSPs or the DatabaseActions.
I would suggest you take the time to read the Cocoon-documentation and browse through the samples, because everything you need is in there. Don't cling too much to the fact that you are using a PocketPC. If your application sends data as an HTTP request, your server can handle it easily; you could develop the entire server-side application using a normal browser as a client and then switch over to the PocketPC... To answer you last question: the StreamGenerator generates XML data from an incoming stream, who's length is not fixed. You won't be needing this, as you are processing normal HTTP GET or POST requests.
