Use the PdfStamper to add a PushbuttonField to an existing PDF. Specify a position on a page, a name for the field, and the page number.

static void AddPushbuttonField(string inputFile, iTextSharp.text.Rectangle buttonPosition, string buttonName, string outputFile)
{
    using (PdfStamper stamper = new PdfStamper(new PdfReader(inputFile), File.Create(outputFile)))
    {
        PushbuttonField buttonField = new PushbuttonField(stamper.Writer, buttonPosition, buttonName);

        stamper.AddAnnotation(buttonField.Field, 1);
        stamper.Close();
    }
}

You should also take a look at iText in Action. Chapter 8 has examples of creating a PushbuttonField and many of the different properties you can set.
