我可以使用Tkinter创建一个Tcl交互式shell吗？

import tkinter as tk
import tkinter.scrolledtext as scrolledtext
import tkinter.messagebox as messagebox
import tkinter.font as font
import tkinter.ttk as ttk
import tkinter.simpledialog as simpledialog

class TclShell:
    def __init__(self, root):
        self.root = root
        self.root.title("Tcl Shell")
        
        # 创建文本框
        self.text = scrolledtext.ScrolledText(root, wrap=tk.WORD)
        self.text.pack(fill=tk.BOTH, expand=True)
        
        # 创建按钮
        self.button = ttk.Button(root, text="执行", command=self.execute_command)
        self.button.pack(side=tk.BOTTOM)
        
        # 设置字体
        self.font = font.Font(family="Courier New", size=12)
        self.text.configure(font=self.font)
        
    def execute_command(self):
        command = self.text.get("end-1c linestart", "end")
        try:
            result = self.root.tk.call(command)
            self.text.insert(tk.END, f"\n{result}")
        except tk.TclError as e:
            messagebox.showerror("Error", str(e))

root = tk.Tk()
shell = TclShell(root)
root.mainloop()
