How to create an application for managing users

[Célio Cidral Junior]

Hi,

I would like to write an application in C# to let someone to manage
users of a MySQL database. It should be able to create, edit and
delete users. Can someone point me out to how I can do that? I really
want to *write* such an application; I don't want to use an existing
client or something.

Regards,
