The computer language used in those pages is PHP. The databases that PHP Runner supports are MySQL, SQL Server and Oracle, remote as well as local.
The creation process of the pages is fulfilled by using an assistant. You'll have to decide the fields that will be shown on the pages, the users than can add content, the functions that will be available, etc.
If you are not happy with the font code generated by the application, you can always modify it manually, adding your own instructions or changing the order of the parts on the pages.
