If you want to "cut" a circle out of the middle of it:

1. make sure there is alpha in the image so we can save a square image 
that looks like a circle
2. make a circular selection with the ellipse selection tool (hold shift 
to ensure a circle)
3. invert the selection, (press ctrl+i) this selects everything but the 
circle so we can delete it
4. delete (just press the delete key)
5. invert the selction (ctrl+i again), this selects the circle again
6. crop to selection (Image->Crop to Selection)
7. canvas size to selection (Image->Fit Canvas to Selection)
7b. optionally now, depending on your application, you can feather the 
selection to make a more gradual edge.  You can play with the number of 
pixels and use ctrl+z to undo in between.
8. Save it/Export it with a new name.
