Red rectangles looks same size for me and spacing is also constant.
Role of spacing rectangles and red rectangles only alternate with spacing white ones. 3 white, 3 red, 3 white ....

Swap the spacing and rectangles after each line:

rect, spacing = spacing, rect

I don't have a lot of time, but here is a simple example to start you, using Tkinter. The other GUI toolkits, WxPython and QT, would be similar.

from Tkinter import *

root = Tk()
root.title('Rectangle Test')
canvas = Canvas(root, width =300, height=300)

## top_left_x, top_left_y, bottom_right_x, bottom_right_y
points_list = [0, 0, 25, 25]
color = "red"

for row in range(3):
    for col in range(3):
        rectang = canvas.create_rectangle(points_list[0], points_list[1], \
                              points_list[2], points_list[3], fill=color)
        ## increase along the x axis
        for point in [0, 2]:
            points_list[point] += 50

    ## move down one row
    if row%2:      ## row is an odd number
        points_list = [ 0, points_list[1]+25, 25, points_list[3]+25]
    else:          ## row is an even number
        points_list = [25, points_list[1]+25, 50, points_list[3]+25]

canvas.pack()
root.mainloop()

The middle rectangle, be it red or white is centered, so if you have a 200x200 canvas, the middle would be 100. You can then move left or right, calculating the end position of the first red square for the rows with 4 red squares; end position=middle - (1.5 white + 1 red). The other row is obviously rectangles of the same size.

John Zelle, Ph.D. teaches Python at Wartburg College
He is the author of graphics.py used by a number of schools instead
of Tkinter


Get the graphics module (a thin wrapper for Tkinter) here ...
http://mcsp.wartburg.edu/zelle/python/graphics.py

also has a nice documentation ...
