I suppose if you are familiar with Tkinter and are happy with how it looks have at it! But there are a ton of things that can be leveraged from Python and Qt separately going this route.
PyQt uses compiled Qt C++ code so isn't really that slow, comparable to how NumPy does it's number crunching. Even if you do find it is slow, you can always come back and branch down to the C++ level when needed, although there are ton of steps you could take to optimize in Python first. There are also all the Qt tools from UI editor and Designer to QML and way more if you really wanna go down the rabbit hole...
What are you suggesting as a really good looking and fast cross platform alternative??
