Bokeh and how to make it into a GUI

I am writing in python and have all my functionalities for analyzing datasets. Now, I would like to turn these functions into a user-ready application that, in a sense, works like an .exe app. In bokeh, I saw that you could create a plot, table...etc; however, is it possible to create a GUI where you can:

1. upload a file for analysis
2. load functions from my written python to analyze the uploaded file
3. graph the results onto a graph
4. click different buttons that can take you to different (so-called) pages so that you can perform different functions.

basically it can go from one page to the other kind of like a webpage where you click one button it links you to the next page for another purpose and home to go back. Could you potentially do this with bokeh?
