How to create raw transaction
Sure :)

My solution was pretty simple:

//String to a private key
DumpedPrivateKey dumpedPrivateKey = DumpedPrivateKey.fromBase58(params, 
        privKey);
ECKey key = dumpedPrivateKey.getKey();

//String to an address
Address address2 = Address.fromBase58(params, address);

Transaction tx = new Transaction(params);
//value is a sum of all inputs, fee is 4013
tx.addOutput(Coin.valueOf(amount-4013), address2);

//utxos is an array of inputs from my wallet
for(UTXO utxo : utxos)
{
    TransactionOutPoint outPoint = new TransactionOutPoint(params, utxo.getIndex(), utxo.getHash());
    //YOU HAVE TO CHANGE THIS
    tx.addSignedInput(outPoint, utxo.getScript(), key, Transaction.SigHash.ALL, true);
}

tx.getConfidence().setSource(TransactionConfidence.Source.SELF);
tx.setPurpose(Transaction.Purpose.USER_PAYMENT);

System.out.println(tx.getHashAsString());
b_peerGroup.GetPeerGroup().broadcastTransaction(tx);
