desktop application

I am not sure if i can explain this but here is what i am interested in. I need to get a simple desktop application created either in visual basic or C++ or something. this program would have to connect to their website so a one time form for them to enter the site url,db info and such would be needed but with the ability to change it later if needed. the program would pull information from the database so they would not have to log in to their admin panel. of course the form to enter the url and db info would be a one time seen theng until chosen to edit from a menu or button. as i said this is a simple program. not looking for anything fancy. i tried to look how to connect to mysql on a site but no luck. prefer a way not to have to do a install but a simple exe would be nice but it would be up to the winner so any information or decent bids would be nice.
