Can I create a form that adds lines whenever a button is pressed?

[someone_somewhere]

Our group has some old forms.  They are adjustable.  We can add and remove lines with the +/- buttons, like so:

This form might be adjusted to:

simply by pressing the "+"button a couple of times.  

However, Adobe tells me it can't edit anything created in "LiveCycle Designer."  We need some additional, but different forms with this property.  

I have a few hundred hours of programming experience, so I can probably just draw lines and move text elements around the screen in javascript, but I was wondering if a more straightforward solution exists in Adobe Acrobat Pro.  

(If not, my only javasript experience is in the browser, so I'd be grateful for a few adobe-specific pointers.)

Things like "Remote Segmentation" and "Glacial Bureaucracy" strongly describe our orginization, so our access to any more advanced tools is limited - nobody even knows who to ask internally.  We'll have to do it with Adobe Acrobat, if we do it at all.

Not possible in Acrobat.

You could create fields in advance and hide them until you need them, but they would still take up space on the page, so it's not dynamically like in "LiveCycle Designer".

Can Javascript create or move fields?  

I'm fairly strong with loops/logic, so I can probably work that out indepedently if some command can be used to draw lines or add or remove text boxes.

Yes, you can create a field with script:

and you can move them around (using 'rect' property):
