Hello and welcome to WebmasterWorld.

Have you looked at the plugin library at WordPress.org? Maybe one of these: [wordpress.org...]

Or look through the documentation - it's very good. [codex.wordpress.org...]

as for any of those sites, you would have to look and see if they have apis available for this type of thing. If so then they should lay out how to accomplish what you want.
