Python programs - what are some simple libraries for UI (graphical interface)?

Question

Python

I created a python script, attached a face from Qt5 to it and compiled it with pyinstaller. The weight of 56 megabytes somehow did not please.

• What simple UI do you know? I don't need much - buttons, checkboxes and displaying messages about processes.
  
• Is the built-in UI suitable for these purposes?
  
• How can the weight of a compiled program be reduced? I do not like the option without compilation because of the spread of my script through the general population.
  

Answer 1

"What simple UI do you know"? - all known UIs are simple.
"Will the built-in UI be suitable for these purposes"? - tkinter will do.
"I don't like the option without compilation for a reason..." - come on, the general public doesn't care.

Answer 2

With regards to Pyinstaller, it is possible to reduce the size of the binary using the --strip option and install the UPX packer into the system (I install it in Ubuntu with the command sudo apt-get install upx-ucl )
