If I forget to renew my driver's licence, can I simply ask for a new one?

You can't apply for a new licence online if you allow your licence to expire, you will have to visit a DriveTest centre. Depending on how long it has been since your licence expired, you may be required to take a vision test (expired for more than a year) or (if it has been expired for more than three years) to retake the full driving test.
