noob question: DAC or GPIO Analog? STM32F3-Discovery

Hi, I have got the need to track a continuously changing value and I had the idea to use D/A conversion to convert my variable into a voltage and track it with an oscilloscope or even voltmeter.

Which should this be done, can a digital value be written to the DAC and then the voltage read on some pin? Or alternatively, is it possible to use a GPIO pin with the GPIO_MODE_ANALOG set for this?
