Every online poker room accepts wire transfers. It is very basic because all you need to do is set it up and the cash will be sent to the specific poker rooms.
Wire tranfers cost money and are slow compared to other methods of depositing into poker accounts. This does not mean that it is not interesting as many people still do it. If you wish to stay anonymous then we highly recommend this form of cash transfer. Do be aware of the fact that it may take a few days before you can actually see your balance and before you can play online for real cash.
Wire transfers used to be very common before the days of e-wallets but now most people just get a free neteller or firepay account as everything is instant. There is no waiting when using e-wallet, all funds are transfered within seconds and players can play almost instantly.
