CustomTkinter VS Forest-ttk-theme

I like CustomTkinter. A UI library based on Tkinter, so you can also use Tkinter along with it.

All tkinter widgets with exceptio of Canvas are currently supported and ttk themed widgets used whenever possible. I plan to add support CustomTkinter eventually.

both custom tkinter and pyqt5 have somewhat "modern" looks.

If you go for tkinter, I recommend you use CustomTkinter instead. It looks much nicer with no extra effort

New GUI based on the splendid work of customtkinter: it is now possible to select files via a "Select files" button instead of the Drag&Drop function that presented several problems this new library allows for much more organized and optimized code the new interface is fully resizable and so adaptable to any screen the new interface also allows more space to add new widgets (in the future) to customize the upscale operations

Well, as I mentioned, customtkinter makes that fairly easy.

In last project I was used customTkinter.

and for a quick overview of other GUI solutions: https://lispcookbook.github.io/cl-cookbook/gui.html (Gtk4, Qt4 and 5, LispWorks' CAPI (incl. for mobile runtimes), IUP…)

I have been pleasantly surprised lately to discover surprisingly nice-looking Tk themes (like https://github.com/rdbende/Forest-ttk-theme). We can use them from CL too, with the nodgui library :) (see link)

For the web, CL & HTMX work well too.

Styling is hard(ish) - compared with CSS, or XAML, it is relatively difficult to style. What seems to work best are using the pre-built themes e.g. forest-dark/forest-light.(https://github.com/rdbende/Forest-ttk-theme) Even with the advent of ttk, there is no common way to style elements. As far as I could tell, this theme e.g. used pngs, there was no way to override individual style elements without actually modifying the underlying style. Ttk styles do help a lot, (I managed a half-way decent pastel-color theme, the issue was with more nitpicky styling management, there are no good defaults), but they are not enough.
