There isn't an application, which let's you remotely control the iPad from a PC. iOS is built in a way, which does not allow anyone to gain full control over the iPad, so it is not possible to remotely control the iPad, unless you jailbreak the iPad, then an app, such as Veency will let you remotely control the iPad.
You can however remotely control a computer from the iPad via apps, such as Splashtop, or Logmein Ignition.
