Help Creating a Scrolling Window

[Shadowflare]

Getting straight to the point, I want to create a scrolling list where the player can choose an option: similar to if you use the Debug window in a playtest, and you go to say, "Add Item"(the additional sprites not included, of course).
I found two functions already in Essentials that I may be able to use: pbListWindow and pbListScreenBlock.

def pbListWindow(cmds,width=256)
  list=Window_CommandPokemon.newWithSize(cmds,0,0,width,Graphics.height)
  list.index=0
  list.rowHeight=24
  pbSetSmallFont(list.contents)
  list.refresh
  return list
end

def pbListScreenBlock(title,lister)
  viewport=Viewport.new(0,0,Graphics.width,Graphics.height)
  viewport.z=99999
  list=pbListWindow([],256)
  list.viewport=viewport
  list.z=2
  title=Window_UnformattedTextPokemon.new(title)
  title.x=256
  title.y=0
  title.width=Graphics.width-256
  title.height=64
  title.viewport=viewport
  title.z=2
  lister.setViewport(viewport)
  selectedmap=-1
  commands=lister.commands
  selindex=lister.startIndex
  if commands.length==0
    value=lister.value(-1)
    lister.dispose
    return value
  end
  list.commands=commands
  list.index=selindex
  loop do
    Graphics.update
    Input.update
    list.update
    if list.index!=selectedmap
      lister.refresh(list.index)
      selectedmap=list.index
    end
    if Input.trigger?(Input::A)
      yield(Input::A, lister.value(selectedmap))
      list.commands=lister.commands
      if list.index==list.commands.length
        list.index=list.commands.length
      end
      lister.refresh(list.index)
    elsif Input.trigger?(Input::C) || (list.doubleclick? rescue false)
      yield(Input::C, lister.value(selectedmap))
      list.commands=lister.commands
      if list.index==list.commands.length
        list.index=list.commands.length
      end
      lister.refresh(list.index)
    elsif Input.trigger?(Input::B)
      break
    end
  end
  lister.dispose
  title.dispose
  list.dispose
  Input.update
end

...but I'm new to Ruby, and even in C++ I was so bad at programming. I'm not sure how to use these, beyond the fact that I'd have to make an entire class for pbListScreenBlock. Can anyone help me in my endeavors?

How do you want to use this list of choices? As part of a dialogue with an NPC? As a debug screen (so looks don't matter)? In a new Pokégear app or something? And what do you want to list?

Thanks for replying, ah...

It'd be a list of "quest" titles--the player could accept one and would have to go and defeat the Pokemon listed in the quest. Somewhat like Monster Hunter, if you've played that. The options in the list would appear as things like "Defeat 10 Raichu," "Defeat a Golurk," etc.

I preferably wanted the quest list as an option to look at in the PC, but if it could only be as a sign on a wall or something, that'd be fine too. The looks do matter a bit, I think I could probably handle how to make the window pretty as long as I knew how to get the scrolling part working.
