What are the limitations on deploying a tkinter gui as a web app?

I have written a tkinter gui in python which involves access to image and excel files. It also has a quite a few buttons and frames to deal with. I built the gui using the pillow library for images, and the openpyxl and pandas library for dealing with excel. I also used the pdf2page library, but I already have a tool to convert pdf to png. Is there a way I can deploy my gui as a web app or run it on a website? If not, is there someway I can recreate a similar interface with the same underlying python code? (that is the code not used to make the tkinter widgets)

I'm planning on using the Django framework - - or something easier - - and A2 web hosting (or similar quality web hosting)
