You could create a custom track and upload it to the UCSC genome  

It looks like you got your info about 90% the way to GFF format:


You could tweak your info a bit, then write.table your way to a file  
you can upload as a UCSC custom track.

Is that good enough, or were you looking for something more? And if  
so, what? There's the GenomeGraphs library, which is pretty slick, but  
I'm not sure if that's really what you're after:


Hope that helps,
