OpenOffice is capable of creating PDFs that are forms (AcroForm).
Instead of an Image, you should use a Button. There's on Open Office
conference in Brussels on June 10; I'll be presenting a demo on how
to use OO in combination with iText during the break.
As soon as I've finished my sample code, I'll put it online.

iText is perfectly capable of finding the position of that button.
AcroFields form = reader.getAcroFields();
float[] positions = form.getFieldPositions(key);
for (int i = 0; i < positions.length; ) {
System.out.print("Page: " + positions[i++]);
System.out.print(" [ " + positions[i++]);
System.out.print(", " + positions[i++]);
System.out.print(", " + positions[i++]);
System.out.print(", " + positions[i++]);
System.out.println(" ]");
}
You can use those positions to add your signature.
