[Inkscape-devel] GUI For Insckape Script Extensions

I noticed the attached slide on Ted's presentation on Inkscape extensions. In the python example available online I see how to use the automatic GUI for scripts to collect text or String data. Can someone point out some examples or documentation that explains how to set up an automatic GUI for a script that uses enumerations or radio buttons?

Would it be possible to use PyGTK from within an Inkscape extension script?

Thanks for the help.
