/diy/ - Do It Yourself

So /diy i don't know if I came to the right board for this but I hoped you know, cause arduino forums don't really answer my question. I plan on using an arduino board for my project but i want it to be connected to my pc via wifi so i can actually control it via the wifi. My question is if I buy Arduino Uno and XBee can i connect it with my pc wireless and send commands to it via regular wifi, or do i have to buy other components for it like arduino wirelles shield or supported chips. No it can't be connected via usb cause the chip will be spinning inside a globe, don't ask. Thanks for your answers
