Change the canvas width, until you can "stretch out" the panorama to its full width. Then, you can select each layer and change it's opacity in the layers menu, and shift them around until they line up the way you want.
Blend the overlapping area into each neighboring layer. Lots of different ways to do that part: use a soft-edged eraser, the smudge tool, etc. You'll want to make the layers 100% opaque at the end, with the edges blended, so you can flatten it all into one layer and make a nice print...
<disclaimer>Never done a panorama, but that's how I'd go about it if I did...</disclaimer> Maybe someone with more experience has an easier technique. :)
