pyqt. how to create custom elements like material design

I love material design. I love jquery, web forms and elements. It have many styles. But when i use PyQt i have default button and checkbox...

I love something like this:

Can I change qt elements so that they become similar to the elements of web-forms? Tell me what to read or may have examples of how to do this already? I just do not know if this is possible because I do not know in which direction to look for ...

i use qt4 and windows... and know only python, not C/C++
