Adding Scheduling to MySQL Database using Gantt

I have a Microsoft Access Database with Scheduling added ([login to view URL]) by Addsoft's Schedox. The company is no more in business how ever the application used for the same can be made available. We need to migrate the Database to MySQL with front-end written similar to the facility we had in Access file. There are few Gantt tools available at [login to view URL] but not sure whether they can be useful. The application will be webbased, multi-user and preferred in MySQL PHP (and if Java needed) however we are also open to ASP.
