You must both plug the Mic into the back of the Wii and connect a Wii remote.
Are you talking about the wii speak or the guitar hero mic?
No, Wii Speak does not work on the computer. Windows will recognize it, but there is no driver for it to work.
The Guitar Hero Mic for Wii is more of a controller itself. You need to sync it with your Wii as if it was a controller.
you plug the end of the mic's wire in the back of the wii consol and make sure you have a wii remote to use with it
No, you cannot play Wii disks on a computer. Wii disks will only work in a Wii or Wii U console.

Most likely you will need a preamp or at least an impedance matching circuit between the mic and the mic in of the computer.

No, the controllers (except the mic) are not cross-system compatible.
