Python:how to create a set of buttons on top of a label in my main window

[jmwhawk]

Brand new to Python. I am looking on advice on how to create a set of buttons on top of a label in my main window.

These 5-6 buttons will be chosen from 3 excel sheets based by the user values set in a QSpinBox (values 1-20) and a QSlider (values 1-3). Then the buttons will be generated by a QButton and each button can be closed after user interaction.

IE: A user setting of QSpinBox "1" will pull randomly from row 1 values and QSLider "1" will select the specific sheet one. Next when QButton is pressed the 5-6 buttons will populate. Clicking on the buttons will generate a note which then can be closed and that button disappears.

So far I have my main window and I can load a user image into a label which I want the random buttons to generate over

from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QLabel, QFileDialog
from PyQt5 import uic
from PyQt5.QtGui import QPixmap
import sys
 
class UI(QMainWindow):
    def __init__(self):
        super(UI, self).__init__()
 
        # Load the ui file
        uic.loadUi("TEST2.ui", self)
 
        # Define widgets
        self.button = self.findChild(QPushButton, "pushButton")
        self.label = self.findChild(QLabel, "label")
 
        # Click The Dropdown Box
        self.button.clicked.connect(self.clicker)
 
        # Show The App
        self.show()
 
    def clicker(self):
        fname = QFileDialog.getOpenFileName(self, "Open File", "c:\\gui\\images", "All Files (*);;PNG Files (*.png);;Jpg Files (*.jpg)")
 
        # Open The Image
        if fname:
            self.pixmap = QPixmap(fname[0])
            # Add Pic to label
            self.label.setPixmap(self.pixmap)
 
# Initialize The App
app = QApplication(sys.argv)
UIWindow = UI()
app.exec_()
