Like I said, I'm no expert. But if all you're using is movepath, then
here's a short summary:

1. You create a directory for your animation.
2. Your animation will be defined by a number of XCF files (one per
frame) with the frame order defined by a number added on to a common
root (frame-0001.xcf is the first frame, frame-0002.xcf is the second
and so on)
3. The easiest thing to do is to start with a blank frame, and use
Video->Duplicate Frames to create the number of frames you'd like
4. The movepath tool (in Video->Movepath) allows you to specify bezier
curves which get interpolated - you define a layer to use, and its
position, set a start point and an end point, let movepath loose, and it
will make the object move smoothly along the path for the frames specified.
5. Movement isn't the only thing you can interpolate - you can also
apply affine transforms (shear, scaling) and change opacity - you just
define, for each point on your curve, the object's scale factor,
transform matrix or opacity, and the interpolation gets dome on its own.
The object gets copied, scaled, and placed on a separate layer for each
layer that you declare.
That should be enough info to start understanding the tutorials at
least. But perhaps what you want to use is OO Present or something
similar - fade effects and things like this are probably easier, and
more appropriate for a presentation. GAP is good for animated GIFs (few
frames) or MPEG videos (many frames, needs lots of memory).
