there a list of things you need to say at the page to describe your program
sourceforge.net's requirement is not that strict, as long as it's free software (it doesn't need to be 100% free software, i.e., it doesn't rely on non-free programs like M$ Windows or Half-Life. This is required at some other sites such as
http://savannah.gnu.org btw.) it will be likely to hosted there
and I also don't think they will check back to see if what you said is true as I have seen quite a lot of vaporwares at that site
