With lots of hand tweaks I quickly made this GUI using
autogui from here:-

You just need to have the files "Gui" and "Gui4Cli" to somewhere
pathed such as your c: assign to use it.

Some systems will need a "GUIs:" assign and If so this should be
as follows:-

assign GUIs: DHx/HDx/Vol:c

and not as follows:-

assign GUIs: c:  ; <- wrong...!!!

eg. assign GUIs: DH0:c  ; <- correct...!!!

So the real full path of "Gui4Cli" is DH0:c/Gui4Cli in this case and
you might want to put the assign in your s:user-startup.


Alternatively you might just want to do a complete auto Gui4Cli install
from here:-

I think the interesting feature of this GUI is that I have coded
check box's to behave like radio buttons.

Changing the default compression from Crm2:-

The compression ID's from Gzip begin from 9 onwards, so if you wanted
to change the default to Lzip that would be an ID of 12 and the defcomp
variable at the top is changed from 25 to 12. 

Feel free to improve this GUI.
