Feature Request: Use `Gooey` to turn this into an app you can use visually

[titanism]

See https://github.com/chriskiehl/Gooey. I tried to get a build working locally, but failed when I got to the pyinstaller -F --windowed build.spec part under https://github.com/chriskiehl/Gooey#packaging. Not too familiar with Python, but thought that you could benefit from adding Gooey to this project so that it would have widespread ease of use (and users wouldn't need to download python/etc).
