PanoTools is the best tool for this job
Good news: it is free
Bad news: it is very hard to learn

If you look in the filters section under distort theres few in there that should be able to sort it out
"shear" is pretty good, also do a "select" >"all" and then look at "edit" >
transform > distort and perspective, you should be able to sort it out without using any extra plugins

Thank you all for your help.

I think you're right, PanoTools seems to be what I was looking for ... I just have to learn to use it :)

Transform > Distort and Perspective is also good for some transformation and I really appreciate the visual way to use it, yet it can't correct barrel, pincushion or spherical distortions.

You should use PTLens as the frontend to it.

This comes in a Photoshop plugin and makes it very easy to use. Well, if you know what lens was used to take the picture.
