Deform image to a specific shape (e.g. ellipse)

[jugoslav]

Hi
Absolutely new to gimp.
0% experience, never used, mot even installed.
Want to use it if one thing is possible.

Is it possible to deform, distort, wrap, do not know right word a photo, usually rectangular shape, but lets say any shape, to a different shape, in this case I would like an ellipse, so the entire photo is deformed, something like stretching a rubber?

So in short any shape photo transform to any other shape deforming the whole photo, not short enough, sorry.

Thank you
