Concurrent Facebook and Twitter Status Update from Web Page

I need PHP code that will post whatever a user enters to their Facebook, Twitter and Wordpress blog at the same time. For this phase of the project all I need is a plain old white page with a section for username/password for Facebook, username/password for Twitter and username/password/rpc endpoint for Wordpress blog, a text field to put an entry into and a submit button. When the user clicks the submit button, the entry is to be posted to their Facebook page, their Twitter account, and their Wordpress blog. This will be developed more later, but at the moment this is all I need.
