Sizers are not visible.  They are strictly used to arrange and position other windows.

Presumably you would know that before you start.  One of the best imaging packages is Pillow, a reimplementation of the Python Imaging Library (PIL).  You would do:

    from PIL import Image
    x = Image.open(‘xxx.png’)
    print( x.size )

The problem with a grid is that the vertical columns end up being pretty long.  That’s why the solitaire apps usually show the card piles as overlapping.

Of course.  After you copy the image to the screen, you can do whatever drawing you want.

You can either use a graphics app like Photoshop or Gimp to create your empty space image, and then treat it exactly like your card images, or just draw to the image box with standard drawing calls.

There are lots of ways.  An image doesn’t have a background color, but you can certainly draw the “negative” of the card.

There are surely lots of card game Python tutorials to get you started.  Start off by drawing some cards and moving them around, before you get into the mechanics of the game.
