For just listening, FLDigi isn't too hard to run. If you are running your radio with it, it can be a bit more complicated initially, until you get it configured the way you want it.
Lastly, I have discovered that sometimes when I leave the program open and come back to it the next day, for some reason it won't kick my transceiver into the transmit mode. Restarting the program fixes it.
There are other programs out there, but for all it's bad points, it's free, common and mostly works pretty well.
Keep at it!
