First I need to explain that GlowScript VPython is compiled to JavaScript in the browser and executed in the browser, so it isn't possible to import Python modules (a partial exception is that many of the random functions are available). It is possible to import modules that are written in JavaScript. I don't know whether there exists a JavaScript library similar to pandas.
I think what you are looking for is VPython 7, which uses installed Python, which means that you can import pandas or numpy or any such module (but presumably not tkinter nor wxpython, as I explained). The VPython syntax is the same as with GlowScript VPython. VPyhon 7 opens a web browser page and uses the GlowScript library to produce the 3D animations.
