Quote: "And possible browser deployment? "
The AppGameKit apps are not deployable via browsers.
They are standalone apps on the device (iOS or Android, etc).
Quote: "Any idea where I can read up on the HTML stuff?"
If you need to interact with a dabase, you must program your server with some sort of language. Straight HTML cannot do database access processes.
PHP is commonly available on most servers (along with MySQL as the database).
If you have a Windows based server, you might have access to SQL Server databases and the possibility of using ASP files (if the server is using Microsft IIS for the web server,
not common on most hosting sites). But I wouldn't recommend that combination. The programming for database access is not anywhere near as simple as with PHP.
