I created a library called CustomTkinter, and with it you can create more or less exactly what is shown in the images above. CustomTkinter provides widgets to be used similar to Tkinter. They can be customised in color and shape, here I tried to create something similar to the image above:

There is not also a button, but many other elements, and it also supports a dark and light theme:

You can check out the library here:

A simple example would be:

import customtkinter

customtkinter.set_appearance_mode("System")
customtkinter.set_default_color_theme("blue")

app = customtkinter.CTk()  # create window
app.geometry("400x240")

def button_callback():
    print("button pressed")

# create button
button = customtkinter.CTkButton(app, command=button_callback)
button.grid(row=0, column=0, padx=20, pady=20)

app.mainloop()

which gives the following on macOS:

Another alternative to create button is to create a label and bind it to the action functions. In the below example .bind() is used to connect the label with respective function. You can design according to your requirements.

from tkinter import *

def OnPressed(event):
    print('Hello')
def OnHover(event):
    But.config(bg='red', fg='white')
def OnLeave(event):
    But.config(bg='white', fg='black')

root = Tk()

But = Label(root, text='Hi', bg='white', relief='groove')
But.place(x=10, y=10, width=100)
But.bind('<Button-1>', OnPressed)
But.bind('<Enter>', OnHover)
But.bind('<Leave>', OnLeave)

root.mainloop()
