Sounds like you should look into a gpsd, which usually provides
(network) APIs for GPS data, but you should be able to push your own
data through it (maybe only geographical coordinates), included tools
like gpsfake come to my mind for a quick start.
Then you can use the standard GPS input in QGIS (or one of the many
other tools able to listen to gpsd).
