Is it possible to create on-line reports that any one can see?

Yes. We often create public reports for internal QPL projects. Typically, we will create a report.htm page that is linked from the main project page, index.htm. On this page we create a form that lets the user pick the report and any report options. We will use JavaScript behind the scenes to build an SQL SELECT query, and then pass the query to a (currently undocumented) program that is already installed in your project web site location called qpl_custom_report_form_public.php, which will automatically run your query and display the results in a table.
