How to custom button and text box using Python GUI?

Question

I would like to ask how to make a custom button and custom text box by using Python?

A custom button should has: transparent feature with only border, round corner, shadow feature, icon need to be placed, animate feature like color changed when click and hover on it.
A custom text box should has: no border but only underline, round corner, transparent feature, icon need to be placed, animate feature like underline becomes thicker when click on it.

Below is my code:

frame = tk.Frame(root, bg='#000000', bd=0)
frame.place(relx=0.5, rely=0.1, relwidth=0.75, relheight=0.1, anchor='n')

entry = tk.Entry(frame, font=60, relief='flat')
entry.place(relwidth=0.65, relheight=1)

button = tk.Button(frame, text="Run", relief='flat', font=40, command=lambda: get_weather(entry.get()))
button.place(relx=0.7, relheight=1, relwidth=0.3)

Here is the reference image design that I prefer:

Any help would be appreciated, thanks!

You sure you want to do this in built-in tkinter? You can explore pyQt5 it has a frontend editor/designer, where you can customize the entire picture then code what each part/button/widget does in python. — Joe, Nov 06 '19 at 17:32
@Joe, hi, thanks for your quick reply, I actually done writing a program by using Python, the problem is it has no GUI. Every time I want to run the program, i need to open 'Sublime Text' or 'Python IDLE' to run it, so I was thinking of creating a GUI for my Python program. Besides using pyQt5, does it possible creates GUI using C# and link to my Python program? — Edison Toh, Nov 06 '19 at 17:51
I feel you man, got a lot of projects like that. I actually created my own desktop app using tkinter for one particular project that I used to run in console. I can say that though a little bit more friendly than in other languages, tkinter proves to be a little hard to use. Specifically in creating a sophisticated design/frontend and also limitations on design options. If you don't mind your app looking like a windows 98 program tkinter will be fine. As far as your problem here goes, there are options you might want to explore in [ttk](https://docs.python.org/3/library/tkinter.ttk.html) — Joe, Nov 06 '19 at 18:07
Ya, tkinter is a little bit hard to use, it is not like Javascript or CSS or C#. I actually kind of mind to my app looking like a windows 98 program, hahaha, that is why I am looking for other option to create GUI rather than using tkinter. — Edison Toh, Nov 06 '19 at 18:38
For the ui design you showed here, C# is the way to go I think hehe! I'm not particularly great at tkinter however, so maybe someone has ideas on how to achieve that ui using tkinter, good luck man happy coding. — Joe, Nov 06 '19 at 18:41
Oh I see, ok, I got it, my last question, does it possible to link C# with Python? Any method could you mind to share with me? — Edison Toh, Nov 06 '19 at 18:44

Tkinter comes with the module ttk which stands for themed tk. It provides a way to create widget themes.

How to do it is under-documented, but tkdocs.com has a good discussion of the fundamentals.

At the end of this question is code which can create frames that have rounded corners, a shadow, and a unique color to represent focus, to serve as an example of what you can do. Answering all your questions is a bit beyond the scope of what stackoverflow is for, but hopefully, this is enough to show that what you want is possible.

Wow, that is great! Thanks a lot, man! However, I was wondering that what if I use C# to create GUI instead of tkinter? I already done writing a Python program, does it possible to link C# with Python? — Edison Toh, Nov 07 '19 at 02:26
