Looking for Software for creating highly detailed GUI

[moo5e]

Hello,
I'm attempting to build a software with high quality user interface(GUI) and 3d visualisation of data. I'm looking for a framework that will only me to do this with relative ease (I don't want to spend months trying to learn this framework). I want to be able to freely design with little or no limitations to for example what a button can look like.
Any suggestions are welcome but please make sure it meets my requirements.
Thank you

I recommend wxPython. It's a very robust and well documented GUI toolkit and I went from 0 to converting a very complex game I'd originally written in tkinter over to wx in just a matter of days. I only have experience with tkinter and wx. The latter is definitely far better.
