Hi Peter 1977, here is the link to the Mobiperl Tools thread. Its stickied along with the GUI thread you shouldn't be able to miss it.
The GUI is setup as per the codes configured in the underlying Mobi2Mobi tools code. Tompe the author has advised that you can directly modify the language using the appropriate HEX code. As you have noted the GUI is not configured to handle HEX code modification of the Language field. The GUI does have a save batch file option which you can use to make your other mods and output the batch file. You can then add the language flag that way. Alternatively you can grab the source code from page 1 of this thread and mod the GUI to add the option. If there is enough interest from other users I'll look at modifying the GUI.
Note: Just as a heads up the language options in the GUI is based on the Language Map specified in the MobiHeader.pm file.
