Here is a simple example of how you can create a GUI with Python using the tkinter library. This program will allow you to add, delete, and count items in a list box.

First, let's create the GUI:

```python
import tkinter as tk
from tkinter import messagebox

# Create the main window
root = tk.Tk()
root.title("List Box Control")

# Create a listbox
listbox = tk.Listbox(root)
listbox.pack(pady=10)

# Create an entry box
entry = tk.Entry(root)
entry.pack(pady=10)

# Create functions to add, delete, and count items
def add_item():
listbox.insert(tk.END, entry.get())
entry.delete(0, tk.END)

def delete_item():
try:
# delete selected item
listbox.delete(listbox.curselection())
except:
messagebox.showinfo("Warning", "No item selected")

def count_items():
messagebox.showinfo("Count", f"Total items: {listbox.size()}")

# Create buttons to call the functions
add_button = tk.Button(root, text="Add Item", command=add_item)
add_button.pack(pady=10)

delete_button = tk.Button(root, text="Delete Item", command=delete_item)
delete_button.pack(pady=10)

count_button = tk.Button(root, text="Count Items", command=count_items)
count_button.pack(pady=10)

# Run the main loop
root.mainloop()
```

In this program:

- We first import the necessary libraries and create the main window.
- We then create a listbox and an entry box.
- We define three functions: `add_item`, `delete_item`, and `count_items`. These functions are used to add an item to the listbox, delete the selected item from the listbox, and count the total number of items in the listbox, respectively.
- We create three buttons and associate each button with one of the functions.
- Finally, we start the main loop to run the application.
