Web application

I am a software developer from Berlin/Germany. I have implemented an application with VFP 9.0 and am going to add web features to it. There are about 85 users that use my program and they want to run simutaniously the programm using the internet connection. It should be posssible for the users to open (in other words run) the application via internet connection to login and enter/edit data on application forms. Would you please help me?

How can a user login to my application, open a form of my application and enter/edit data on a (form)graphical user interface using internet (web) connection?

many thanks in advance
