The scenario you describe should be fulfilled by a web application.

I'm sure your users are also able to use a browser, not only Excel.

The HTML forms management offers the GUI capabilities to enter the 
parameters. The processing steps could be as follows:

1. Enter the url for the application in question and display the form.
2. Enter the needed data in the form.
3. Process the data (with lots of your python scripts) and show the 
result in the browser.
4. If all is ok, download the data sheet in Excel format (using 
DataFrame.to_excel)
