Maybe pythondialog could be useful for this. I've never used it so I 
can't really tell if it will fit your requirements, but at least it 
seems worth a look. It looks like it supports text input with a default 
value 
(https://pythondialog.sourceforge.io/doc/widgets.html#single-line-input-fields). 
The other thing you describe is, if I understand correctly, an input 
with predefined values but also the ability to enter a custom value. At 
first sight that doesn't seem to be provided.
