Looking for comparable technology in Linux (Borland Midas and ADO)

Can anyone tell me if there are similar products or technology that are available in Linux that will allow me to duplicate an application I have written in Borland - Delphi with Midas. It's an app that I can send to users which allows a user to login to an application which will let the user add/delete/update their web content that is stored in a database. It has ADO Connection and queries on the server side and Socket connection with 'client data sets' on the client side of the app and I'm trying to find something that I can use that will replace this functionality. I'm hoping that this very brief description is clear enough and hoping that anyone who has developed on this platform will understand. If not, please ask for clarification and thanks for any and all input.
Regards,
Lee Catlett
