[Tutor] Wondering about a project

[dw]

Hi Python gang.
In my Ubuntu system, I'm pondering a first GUI Python project:
1) Prompt for a user input string.
    The intended string would be a youtube URL
2) Call youtube-dl to download the file
3) When the file is downloaded, call GnomePlayer or VLC to play the file

I'm new at Python and haven't built a GUI application yet.
I wonder if this project would be over my head?
Perhaps I should attempt to build it in terminal mode first?
