I couldn’t believe myself at first, but it’s true!! I’ve been searching since a very long time ago for a decent (and free) PDF editor, especially on my Linux box (but it’s available for Windows and many other platforms as well) and I found this very nice plugin for Open Office that lets you very easily open and edit PDF files, they said it’s not for very big changes, but I tried editing 2 random PDF files on my laptop and it worked pretty fine, here is the link:

Enjoooooooooy!!

Note: This only works with Open Office 3 and above, and to install an extension just click Tools -> Extension Manager -> Add, then choose your file and I think you’ll have to restart the Open Office.
