First, load up your image and open the Layers dialog. (Dialogs > Layers & Channels)

Right-click on the word "Background" in the Layers dialog. Select "Add Alpha Channel." Then, under the same menu, select "Add Layer Mask." The default layer mask options are fine, so you can just click OK in the dialog that pops up.
