Yes, because you appear to be using Victor's NTL code directly within your plugin (I assume from your inclusion of Victor's license info). Therefore, your plugin becomes GPL by direct reference unfortunately. As to your giving your plugin away, you are not directly affected by the GPL restrictions, but for commercial entities, the GPL prohibits our use within a non-GPL'd application; even if we were publishing the source of our app and wanted to release it under a different license such as the BSD or Mozilla licenses, we couldn't include GPL'd code.
