Perhaps a bit late Jabbae46, but all you need is a small screwdriver (or a couple) to prise out the horn push (disconnect battery first or you **** of all the neighbours) and a socket (19mm IIRC) on a short extension.
Then just rock the wheel while pulling it gently. Top tip - Don't take the nut off all the way to start with otherwise you are likely to smack yourself on the nose with the wheel
