The amounts you owe for Liability and Credit Card accounts appears on the Balance Sheet report and also on the Chart of Accounts.
To create a custom report with less details than the balance sheet, with rows only for the desired accounts:
1. Start on the Reports menu and pick Custom Reports | Summary.
2. On the Display tab, pick Display columns by = Total only and Display rows by = Account List.
3. On the Filters tab, remove the Date filter and change the Account filter by picking "Multiple Accounts..." from near the top of the list and then select the desired liability and credit card accounts.
Then run the report to see the balances.
