Wow, that's a tall order, Barb.
Amano's tank is professionally done, with what looks like a lot of Java Ferns, and a full carpet of HC. And there is no doubt it was set up with the knowledge of someone who has good experience with discus.
A difficult job for someone who has no experience with discus, and even more problematic for anyone who hasn't successfully maintained a well-planted high-tech freshwater tank.
I believe you would do well to take some baby steps first.
At the outset, I suggest you do a lot of research on keeping discus, which require somewhat more care and attention, not to mention high quality water conditions, than most other species of fish.
You could begin by having a read of my 'Beginner's Guide to Getting Started with Discus' -located here as the initial Sticky in the 'Fish' section.
When you've done that, and got your mind wrapped around what it takes to successfully keep discus, then you could cycle and prepare your tank properly to give yourself an honest chance to succeed with these gorgeous fish.
While a planted tank environment is not the best way to start keeping discus, it can be done, and I'd be happy to try & guide you through it, until you become quite familiar with discus traits & behaviors, and are prepared to take the next step, and kick up your planting a notch by proceeding to a high-tech, pressurized CO2 environment.
Am I reaching you ?
Frankly, there's a lot of info you need, and not enough time here to go into more detail at the moment.
Meantime, have a look at my modest, low-tech planted discus tank, which takes a good deal of my attention to maintain properly over a long term basis, in order to succeed without endangering the health of these beautiful fish - and that's with quite a few years of experience raising discus behind me:
