Show HN: Python GUI with tkinter and a Markdown-type language for describing it

v1, lots of code and redundancy

  def main():
     global user_info_text
     root = tk.Tk()
     root.title("Okta")
 
     main_frame = ttk.Frame(root)
     main_frame.grid(row=0, sticky='w', padx=10, pady=10)
     
     ttk.Label(main_frame, text="Okta URL:").grid(row=0, sticky='w')
     url_entry = ttk.Entry(main_frame, width=40)
     url_entry.insert(0, okta_url)
     url_entry.grid(row=1, sticky='w')
 
     ttk.Label(main_frame, text="Username:").grid(row=2, sticky='w')
     username_entry = ttk.Entry(main_frame, width=40)
     username_entry.insert(0, username)
     username_entry.grid(row=3, sticky='w')
 
     ttk.Label(main_frame, text="Password:").grid(row=4, sticky='w')
     password_entry = ttk.Entry(main_frame, show="*", width=40)
     password_entry.grid(row=5, sticky='w')
     command = lambda _=None: sign_in(url_entry.get(), username_entry.get(), password_entry.get())
     password_entry.bind("<Return>", command)
     password_entry.focus()
 
     ttk.Button(main_frame, text="Sign In", command=command).grid(row=6, sticky='w')
 
     ttk.Label(main_frame, text="User Info:").grid(row=7, sticky='w')
     user_info_text = ScrolledText(main_frame, wrap=tk.WORD, width=100, height=30)
     user_info_text.grid(row=8, sticky='w')
     root.mainloop()

v2, refactor and invent a markdown-type language for the GUI:

  Label
  _Entry_
  _*_     (Password Entry)
  [Button]
  |ScrolledText|

Does something like this already exist?

code:

  def main():
     global user_info_text
     root, url_entry, username_entry, password_entry, sign_in_button, user_info_text = gui(f"""
         Okta URL
         _{okta_url}_
         Username
         _{username}_
         Password
         _*_
         [Sign In]
         User Info
         |text|
     """)

     command = lambda _=None: sign_in(url_entry.get(), username_entry.get(), password_entry.get())
     sign_in_button['command'] = command
     password_entry.bind("<Return>", command)
     password_entry.focus()
     root.mainloop()
 
  def gui(s):
     root = tk.Tk()
     root.title("Okta")
 
     main_frame = ttk.Frame(root)
     main_frame.grid(row=0, sticky='w', padx=10, pady=10)
 
     ws = [root]
     for row, w in enumerate(w.strip() for w in s.split('\n') if w.strip()):
         text = w[1:-1]
         if w.startswith('_'):
             show, text = (text, '') if text == '*' else ('', text)
             w = ttk.Entry(main_frame, width=40, show=show)
             w.insert(0, text)
         elif w.startswith('['):
             w = ttk.Button(main_frame, text=text)
         elif w.startswith('|'):
             w = ScrolledText(main_frame, wrap=tk.WORD, width=100, height=30)
         else:
             w = ttk.Label(main_frame, text=w + ':')
         w.grid(row=row, sticky='w')
         if not isinstance(w, ttk.Label): ws.append(w)
     return ws
