Ok ... if you don't know what you are doing in QB then you can get real lost real quick so getting some education on how to properly enter things would be highly recommended. The QB program will do everything you need/want however if you don't understand the basic principles of double entry bookkeeping you can mess things up badly.
Basics for your situation would be :
Loan from shareholder for the cost of the asset and an addition to assets for the balancing act. And then the payments made thru the business bank account of the principle on the CC will be repayment of loan from shareholder and any interest is an expense.
