What GMan said should be considered........I have never kept either of those frogs so I have no input there..but I do have a few simple viveriums for my darts.
I have a 20long viv that has two seperate sections for two different PODs, a 10 gallon viv with one POD, a 20 tall with just plants right now (waiting on a POD)....and a little 5gallon river tank. The only one with water is the 5gallon river tank.
There are many different things you can do with a viv....alot of folks use egg crate to seperate the water area from the planted section....so that any water that does wik into the substrate drains through and doesn't saturate the soil.
That would be a simple enough project to have a layer of egg crate at the bottom......a layer of this stuff

(cocoa bedding is best for vivs...drains very well. You can soak it in water with liquid plant fertilizer..make sure the fertilizer you use is ok to use for frogs, no chemicals and stuff)
You could easily work something up for a waterfall design using one of those little whisper intank filters. Put one of those where you want your waterfall and just silicone rocks/wood around it so that the water flows down and into your "pool" area. Of course, you would want to fix this up so that you can pull the filter out if you ever need to. You would also want to make sure that your frogs couldn't fall down underneath the eggcrate....so perhaps just a pile of larger riverstones for the water to fall onto and through the eggcrate. You could be creative if you want a pool of sorts, by just having a piece of wood or something that has a natural "dish" which could just collect water at the base of the filter.
I don't know if you can picture any of this....lol......I'm not that good at paint, but here's an attempt to give you a pic of what I'm talking about....
This would be simple enough to do in a 10gallon tank. Be creative in what you do to hide the filter or make it fit into the plan.
Have fun setting this up...and do post some pics !
