There isn't one.
Also, if you were using a recent version of Bitcoin-Qt, there is a good chance that pywallet won't work properly anyway, as the wallet file format was updated/changed since pywallet was last updated (late 2014!!?!).
The script chokes on a bunch of "unknown" and/or "unexpected" data fields if I remember correctly...
Python scripts and operating from the command line aren't really "non-techie"... You'll just have to read the pywallet thread and use Google
