Oh, but you can — unless the Ctrl-Tab event doesn't reach Vim, or
reaches it as a plain 0x09.

My gvim can see whether or not Esc, Tab, Enter or Space has been hit
with or without Ctrl and/or Shift: try it, in Insert mode in gvim, by
hitting Ctrl-K followed by Shift-Space, Ctrl-Tab, Shift-Ctrl-Esc, etc.
You'll see the correct <> code inserted in your buffer, even though
Shift-Space normally inserts a space, Esc is Ctrl-[, Tab is Ctrl-I,
Enter is Ctrl-M. I think I've seen a bug fix about that recently (well,
before the 7.3 release obviously) but I can't find it back.

if has('windows')

noremap <expr> <C-S-Tab> <SID>Tab(0)
function s:Tab(fwd)
if tabpagenr('$') > 1
return a:fwd? "\<C-PageDown>" : "\<C-PageUp>"
else
return "\<C-W>" . (a:fwd? "w" : "W")
endif
endfunction
endif
