If you were to manually input transactions on my bitcoin-qt and put it on two computers and then get two computers to authorise the transactions due to how it is mined. Which would mean you were earning bitcoins by coding in transactions into blockchains which could be confirmed by computers through the mining process.
NO. ABSOLUTELY NOT. Please read some more about Bitcoin. You would be creating a fork of the blockchain which would not be accepted by the Bitcoin network. Your transactions would not be valid since a previous input is not valid and such a plan would not work. Also, please read up on Bitcoin, preferably the white paper by Satoshi. Miners do not authorise transactions, they simply verify transactions (which all full nodes do) and include them in blocks securing them with cryptography to prevent double spends.
