Is quite simple to do in bitcoinj. Do you have a format in mind? If so send me an sample will see what I can do. Please DOUBLE check it is signed correctly! Make it a transaction that sends to my address below and I will have more motivation!
I was thinking that if www.bitaddress.org could also create/sign transactions (not trival as need to link all the inputs), then if you had this web site you could then create transaction totally offline.

I just created a tx, transferring 1.0 BTC to the address in your signature. I plugged this tx and the previous one into my ECDSA unit-test (which works on other Blockchain tx-pairs) and it passed. So I'm fairly confident that this is signed correctly. Here's the raw hex:

Code:

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

And a pretty version of it:

@btc_novice: I'll happily toss you a BTC too, to test your solution, if you get something running.
