GIMP :: Cut Out / Lasso Item In Picture And Not Have Black Or White Background?

I just want to cut out/lasso an item in a pic and not have a black or white background..just the item itself..

I have *picked a photo
*click layer
*chose transparency
*added alpha channel*
*cut/lasso item out
*selected invert
*pressed delete on keyboard
*pressed select and none

I then get this picture which looks perfect right???

But when I copy and paste it or open file in paint or anywhere else it ends up like this? I want just the cut out and not the background too but no matter what I do the stupid thing comes with..
