odd bike frame size
i have a 50 cm bike and i am 6'1". before you start— i have short legs for my size. they tried to fit me on a 56 cm and my legs couldn't reach the pedals much less the ground. however, my height comes from my torso. so although i'm comfortable heightwise on the bike, i have bullhorn handlebars and i can't use them properly because my torso is so long, that if i bend over, i'm past the range of the handlebars. i'm probably going to have to get a handlebar that is suitable for riding upright, because currently it's very difficult to ride upright with bullhorns.
my question is, do they make bike frames with a shorter seat tube, say, around 52 cm, with a much longer top tube than is normally put on those bikes?

You could try to go with a mountain bike frame, they tend to have long top tubes relative to the seat tube. A custom frame may be something else to consider. If you really are having a lot of trouble then the cost of a custom frame may be worth it over the hassle of trying to get something else to work.

Ability to reach the ground while in the saddle is overrated.
+1 on MTB. Some mid-90s XC frames have super long top tubes.
My KHS has 50cm seat tube (to top of tube) and 60cm effective top tube.

I guess one could start looking for a frame with sloping top tube and appropriate dropouts or track ends.
might want to check out salsa bikes. They offer MTB frames that will work with SS/FG.

Vilano's are reputed to have a very long toptube for their sizes. For that matter, the 09 Fuji Track pro has a constant seat tube length and only varies the top tube. Because the seatpost is integrated you have to cut it to the right length. In your case you could get one with the right top tube length (use a fit calculator) and then cut the seat mast down to the appropriate height. I actually have almost the opposite issue on my FTP in that the toptube is the right length but I barely had to cut any of the seat mast down and if I were any taller I would be worried about the geometry.
Also, you should probably make sure that you have short cranks, 165mm or less, as these will both be easier to reach and probably more efficient.
edit: I see you already have a vilano so maybe the reputation of having a long top tube isn't deserved.

i know that leader also has (or at least had) long top tubes. i ride a 58, and i swear that top tube is significantly longer than that seat tube. it's a 721 v2, and i have to ride a 60mm stem on it to compensate for the longer top tube. my lo pro, in comparison, has a 100 on it.

FGFS frames are good for this because of the negative bottom bracket drop.
Something like a medium Charge Scissor will have a 52cm seat tube with a 56cm top tube.

You can put some ape hangers or medium sized risers on your bike and rotate them outward. Pretty comfy riding.

Thanks everybody! I appreciate the advice. At this point probably what I am going to do is get some risers so I can ride upright. If and when I get another bike I'll make sure it's long enough before I make sure it's short enough.

The leader 725/735 have really long TT's, as mentioned earlier. I'd go with that.

I agree that it's an odd geometry.
Here is that same bike (I think) in action:
