Owen's information is unrelated to what you want, assuming you mean
total transparency. (if you mean partial transparency, GIF doesn't
support it -- PNG does, though)

First, The layer must have an alpha channel. Right click on the layer
in the layers dialog and select 'add alpha channel'. If it's grayed
out, it already has an alpha channel.

Second, you must cut out the areas you want to be transparent. If you
are trying to do color-keying, the 'select by color' tool will
probably be helpful (followed by Edit->Clear to clear the area)

You can then export a GIF (or save one, depending on whether you are
using a new or old version of GIMP)
