Perhaps I'm missing something here, but what's impossible about it?  With 
wget, it checks the size sent by the http server, so it should tell you if 
the download is incomplete.  As you probably know, md5sum is standard on any 
Linux installation, so just run md5sum on the downloaded file.  This could 
be done with a script.  You would somehow have to get the correct md5 
checksum by hand or put it in a file, but it's easy enough to tell with 
manual inspection whether they match or not.  Also, wget can resume broken 
downloads in most cases.  I know curl and ncftp can as well.  Regarding GPG, 
just use "gpg --verify" to verify the download provided that you have the 
GPG signature.  Again, that could be done with a script which first calls 
wget to download the file.  All of this is unnecessary if you download by 
hand from the ftp site I mentioned.
