As far as I can read in gtk-radio_button.ads the followinf dtatements 
should do the trick:

       TypeDialog.Radio_Frame := Widget_SList.Null_List;
       TypeDialog.Radio_Header := 
Gtk_Radio_Button_New_With_Label(TypeDialog.Radio_Frame,To_String(Ext_C_Header(lan)));
       TypeDialog.Radio_CPP := 
Gtk_Radio_Button_New_With_Label(TypeDialog.Radio_Frame, 
To_String(Ext_CPP_Header(lan)));

       Pack_Start
         (TypeDialog.Radio_Button_Box,
          TypeDialog.Radio_Header,
          Expand  => True,
          Fill    => True,
          Padding => 0);
       Pack_Start
         (TypeDialog.Radio_Button_Box,
          TypeDialog.Radio_CPP,
          Expand  => True,
          Fill    => True,
          Padding => 1);

But the dialog looks good with the exception that both buttons are 
activated and cannot be deactivated. I still do want the choice between 
the two I cannot find that in the When running in debugging mode I can 
see that the group still is null
