Need jscript programmer or guidance

Hi list, in Pure Data I use the data structures objects to display the time structure of a score, as displayed here (all these elements are dinamically created when reading a score file, all information is read from a file):

I wanted to do the same in Max, which comprises:

- the elements to display are only a combination of numbers/strings and vertical lines (of different sizes and thickness), some of them with different colors.
- internally there is saved information such as X+Y positions, other numbers and strings.

- there should be interaction in the black lines: when they're clicked with the mouse, they send their internal data to a receive object.

- such scores must be displayed in a normal dedicated window, as they can be quite long (up to some hours duration), and window sliders are necessary to browse through them.

Creating the objects dinamically isn't an issue, I already did a test using canvas objects. But max doesn't allow to query them, so it seems to me that jsui objects would be necessary; only I don't know how to work with java.
The final question is: is there someone who would like to point me in the correct direction (in case some similar templates exist), or to do this programming in comission?

Best,
Joao
