This rig is designed to be LSB in conformity of ordinary SSB usage. It can easily be converted to USB by changing the IF frequency (and the band, of course). Think 60m.
It can become CW capable by either: 1)injecting an audio tone into the LSB signal (instead of a voice signal), or 2) unbalancing the BFO mixer to allow some of the suppressed carrier through. This will also involve changing the IF slightly (though one can usually get away with it by leaving things more or less as they are). However, note that CW requires a much narrower filter than SSB; you will have to accommodate that somehow.
For the software, begin by looking at Farhan's software for the "Mimima" transceiver. If I am not mistaken, that is where he began.
I agree with Jack in that you should get to know the Arduino. Parts are cheap; instruction is everywhere on the web and the programming software is free and easily installed. Like everything else worthwhile, there is a learning curve involved but I'm sure that you are up to it. Google "Arduino" and be prepared for inundation!
With a DDS, PSK or any of the other digital modes is easily handled, even WSPR. The original FCC-2 had a PSK input as standard equipment.
Hope this helps.
