If you would want to make tkinter app a little bit nicer looking you could use theme like this one.

You can make tkinter look good with this or this.

Surprisingly more than ever! There are a few libraries and themes that make it look very good. This one and this one are both amazing

Move to html/css for your interface or for desktop only Tkinter with some new looks. And if you need really complex stuff, there's PySide6.

Easily themable (some great themes here).

Matplotlib or Plotly will give you grafana style plots, the rest of what you want (Buttons, Entry Boxes, Labels) is all in Tkinter! If you don't like the look of tkinter, you can change it with this, this or this. (that last one is my favorite).

Also with the new tkinter themes provided here, tkinter is having a micro-resurgence thanks to its new look.

But I recently found this beautiful theme for ttk and some customizations for tkinter that made me look twice before going to the PySide. If your UI does not need complex interaction, tkinter can look really good.

For native GUI, DearPyGui[0] as modern as you can.

For browser web-based GUI, you can use nicegui[1]

If it's just to align text in the centre or to the right of a box, you could use a button and, by using theming, hide the fact that it's a button. https://github.com/hoffstadt/DearPyGui/issues/1111

Personally, i like PyQt or PySide they have basically everything you need to make a proper app or even simple apps, but there is another DearPyGui this is basically python version of imgui the c++ library, it provides some good customization options and can be used for simple or complex projects too, their discord is also very helpful.

There are some examples in the showcase as well. https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase

I'm a big fan of DearPyGUI

Use a button and set width of the button equal to the width of the window. Using theming to set the button text alignment to center. A comparable solution, for aligning to the right, can be found here. https://github.com/hoffstadt/DearPyGui/issues/1111

I was using PyQt5/PySide which will give you a nice native look but I eventually shifted over to DearPyGui for most of my smaller utilities. Its just faster for me. You will get more options and freedom with PyQt/PySide though and can use QT Designer to design your interfaces pretty easily.
