You can use i3 modes for this purpose. Pressing $mod+Shift+q moves you to a special mode, where it asks you if you really want to close the window. Then, in my example, pressing Enter or y will close the window. Pressing Escape or n will get you out of this mode.

set $close "Close the window? (y/n)"

mode $close {
    bindsym y kill, mode default
    bindsym Return kill, mode default

    bindsym n mode default
    bindsym Escape mode default
}

bindsym $mod+Shift+q mode $close

This is not perfect, but perhaps you'll like it.

Sure, but not from i3 itself. You can change your keybinding to execute this:

bindsym $mod+Shift+q exec --no-startup-id xdotool getactivewindow | xargs -I '{}' i3-nagbar -t warning -m "Do you really want to close this?" -b "Yes" "killall i3-nagbar; i3-msg [id='{}'] kill" -b "No" "killall i3-nagbar; i3-msg nop"

Not exactly pretty, but works. I don't think i3-nagbar is a great tool for this, though, but you can replace it with whatever tool you want to create the dialog with. For example, you can use zenity:

bindsym $mod+Shift+q exec --no-startup-id xdotool getactivewindow | xargs -I '{}' zenity --question && i3-msg [id='{}'] kill

I use xdotool to get the focused window first because if I simply do the dialog and kall i3-msg kill, you end up killing the wrong window.
