Which Front End for Postgresql

Which software should I use for a front end for Postgresql? I know I
need an admistrator package for the databases, don't I?

What about which software to write the enduser routines? The input
screens, etc?

come to think of it, what software should I use for reporting on the
internal network?

And what should I use for publishing data on the Net?

Thanks for any help,

Al
