Need help to make and query cost matrix table?

I had built a website for my client with Drupal 6 . Now he wants to query cost of his service from one town to another 开发者_StackOverflowtown. I know basics of CCK and Views. I will need two select box for towns and show cost of between two towns and a way to let customer enter cost between towns. What is the easiest way of doing it in Drupal ? I am a java guy no PHP experience.

Edit:tablefield look promising. I need a way filter it view module. If I will succeed will write how to do it here.

As a hack-type solution, you could do this:

1. Create a new content (node) type, say, "Transport Routes".
2. In it, define CCK fields From town, To town, Cost.
3. Create a new View, which would display the Cost field.
4. For the above view, enable two filters on the From and To fields, and make these filters accessible to the user.

It does sound very awkward, I know, and a better solution is probably to write a simple custom module, yet if you prefer to stay away from PHP - this is one way to do it.
