Yeah - you are trying to do something fairly advanced.
Once you have tried to make some programs (and you may want to read my blog - link below), and have become famillar with the visual components (Text, Graphic, Panel, Scroller, Repeater, Clip etc), you can then try to implement your idea.
Always start by grabbing a piece of paper and DRAWING what you want your interface to be.
So in this example, we start with your horizontal line. This is a scrolling region - so you will need a scroller. One that lays out it's parts - the individual options in each strip - horizontally.
Then you will want a number of these, moving down the page. And again, they will scroll. So you will need another scroller, this time scrolling vertically.
It's not particularly difficult once you know what's going on in MCML, but I'd start with getting simple buttons working, then move on to a vertically-scrolling list of buttons, then keep adding more in that way.
