how do I delete 'wine' application?

Hi I have OSX 10.8.3 and have been trying to load up an old music compliation which I had for windows xp.

Reading forums I decide to download Wine bottler as my cd wouldn't boot up. Howver having read all the warnings I decidec to uninsatll the said, but am trying to delete wine as this is all that's left in my application folder from wine bottle.

Any help would be appreciated to to enable me to delte / move to trash - it keeps telling that I can't move it to the trash as it is still open. Howver I can't see it open.
