Is it possible to create a Streamlit web application that uses PyQt as a kind of launcher?

I’m trying to create a machine learning application using Streamlit.
For sompany policy reasons, the data I use should be pre-processed using PyQt.
However, I want to visualize the result using Streamlit. What I want to is when I push the button on PyQt App, it pops up the streamlit web application and it shows the simple data analysis web application.
Unfortunately, I have never seen such applications and examples.

Do you think it is possible?
If so, is there any example code?
