Help?

Is there anyway to do wireless sync across iTunes on a laptop and a 4th Gen iPod?

I've lost the cable, not to mentioned that its like the 3rd Cable I've had to buy due to how fast the cable tears and wears out, I'm not using a MacBook or any iMac, so downloading an App out of the Mac Store is out of the question, I'm using an HP Laptop running W7, are there any apps that I can download TO the iPod and sync it with the iTunes on my Windows laptop? I know the easiest thing would be to hurry to my local BestBuy and buy a new cable, but im pretty sick of buying 3 or 4 cables per year cause they keep wearing out like I said

Thanks in advance, in the meantime I'll continue to search on my own.
