Feasibility of djano and elfinder interface

I'm trying to determine the software I want to use to develop a web based GUI. (For this project)

The main goal of the interface is to let the user interact with files and (for example using a custom right click menu) launch Python function on the selected files.

The software I was thinking to use are django and elfinder. The server would be completely implemented in django and would present the elfinder interface to select/rename/move the files.

Custom menu items in elfinder would launch Python functions on the selected files.

Before embarking in this project (Since I barely know how to use Flask) I'd like to have some opinions and directions on the feasibility of this project with these tools and possibly a minimal example on how to start.
