I'm not sure about a "wordpress website" but the rest is all possible. If you plan on using Instant Web Publishing (as opposed to custom web publishing with PHP), your choices are FileMaker Pro or FileMaker Server Advanced. Hosting the DB from Pro supports up to 5 simultaneous connections from web browser clients. Server Advanced supports a much larger number. Another option is to contract with a web hosting company to have them host your FileMaker Database to the web for you.
