Ability or inability

Hello dear boden team
I am very interested in boden framework but due to a lack of resources and statements from friends and relatives, I have become discouraged by boden framework .
My friends at the university and around me tell me that with boden framework you can not implement and develop advanced UIs for mobile devices and you should use flutter and react native for advanced UIs, for example, UIs such as the link below can not be used. Implemented in boden framework :

and
https://search.muz.li/ZjcyYjQ1Yzhl
so can i implement like this ui with boden framework ?and how?
and I have some question:
can I use other api with other language like python for backend?

Please answer all my questions and guide me
