if you're brave and you have a leap of faith to trust a newbie, here's my attempt to compile the windows wallet:
http://f4k3.net/~fake/Iridium-qt.zipit should contain all of the required things (and maybe a tad more to make sure) and should work on 32- and 64bit windows versions (being 32bit).
let me know how it works out for you. it should work on windows. if not, we both will learn something

if you are happy, IDR donations are appreciated: ir3Wx7ug1PV3JHXGkShhQg15afywZamSWKr5iT7PiBtxgYDK8WTpLiBVNVU7j5anBTVGujaXQV6JEjB

if you are not happy, get some ice cream or a coffee or whatever makes your boat float

edit: for the lack of http_s_, here's the SHA256-sum for that archive: 7fbac156891a49aa4a4f922d0787fc53b84ac8a8d0df9dfe0d1cf20539df071a
I will spend more time on it but I can't get it to pick up my .wallet file so it just keeps starting up with your IDR wallet ID.
