I would like to create a GUI that pops up asking where to download a file using python. I would like it to be similar to the interface that Google Chrome uses when downloading a file as that looks pretty standard. Is there a default module or add on that I can use to create thus GUI? or will I have to create myself? any help would be appreciated.
There are a number of GUI toolkits you could use, including:

Kivy (modern touch-enabled) 
Tkinter (bundled with Python)

These have file chooser widgets, which you could use that would provide standard-looking interfaces to your file system.
How do you want to run this program?
