Create menu to edit vertices

Question

I am not a programmer but managed to write a python script to draw a slab (Cube) with lots of vertices. I want to create a menu that will list the z values only and allow me to edit them. It is very difficult to go into the python script and try to edit the z values. Is it even possible to do in blender? I know I can use Transform to edit as well but it takes too long too especially if my slab is big and has a lot of elevations.

My goal is to get something like this below.

I'm not sure how easy this really is to use, but here's a script with a list of heights you can edit.

import bpy

# ===== Edit these! =====
width = 5         # number of verts in each row
height = 5        # number of verts in each column
side_length = 5   # side length of grid square
heights = [
    5.0, 5.0, 5.0, 5.0, 5.0,
    5.0, 4.0, 3.0, 4.0, 5.0,
    5.0, 3.0, 2.0, 4.0, 5.0,
    5.0, 2.0, 2.0, 3.0, 5.0,
    5.0, 2.0, 1.0, 1.0, 5.0,
]

#Build vertices
verts = []
for y in range(height):
    for x in range(width):
        h = heights[(height-1-y)*width + x]
        verts.append((x*side_length, y*side_length, 0))
        verts.append((x*side_length, y*side_length, h))

#Build faces
faces = []
r = 2 * width  # verts per row (one bottom + one top)
for y in range(height - 1):
    for x in range(width - 1):
        i = r*y + 2*x
        faces.append((i+2, i, i+r, i+r+2))                            # Bottom
        faces.append((i+3, i+r+3, i+r+1, i+1))                        # Top
        if y == 0: faces.append((i+1, i, i+2, i+3))                   # -Y Side
        if y == height - 2: faces.append((i+r+1, i+r+3, i+r+2, i+r))  # +Y Side
        if x == 0: faces.append((i, i+1, i+r+1, i+r))                 # -X Side
        if x == width - 2: faces.append((i+3, i+2, i+r+2, i+r+3))     # +X Side

#Define mesh and object
mesh = bpy.data.meshes.new("Cube")
object = bpy.data.objects.new("Cube", mesh)

#Set location and scene of object
object.location = bpy.context.scene.cursor.location
bpy.context.collection.objects.link(object)

#Create mesh
mesh.from_pydata(verts, [], faces)
mesh.update(calc_edges=True)
