Advice on developing a product catalog/menu for a small retail site. [View all]

I own a small retail store. The products might be a simple flavor (banana, cherry, watermelon, etc) or might be more complex (a creamy butterscotch with a touches of citrus and berrys).

The simple flavors are generally "house flavors" that we create ourselves and the more complex ones are generally "branded" flavors that we purchase pre-made.

We currently use printed menus that people can look thru to find a flavor they are interested in. These are clumsy and expensive to update.

What I "see" is a touch-screen mounted on the wall. A customer could come in and type "citrus" or "fruit" or "creamy" or "banana" etc in a search box on the screen and it would display the different items that match the criteria.

I am somewhat familiar with networking (I maintain a small private network that serves flat files to 10 boxes).

I am somewhat familiar with simple HTML (I set up the Apache server and developed the flat webpages that allow users of the network to select the file they wish to view/download).

I am somewhat familiar with Wordpress (I maintain my retail store's website, but it was developed by a person I contracted for that).

My questions are:

1) Is there a simple easy way to do this? A program I can download to the tablet/Ipad, etc, fill with data and hang it on the wall, no networking, html, http involved?

2) If the answer above is "No", would it be better to set up the Apache server on the tablet itself and have all the requests go to 127.0.0.1/xxx/xxx or would it be better to set the server up on a separate computer and have all the requests go to 10.0.0.1/xxx/xxx

3) Also, if the answer to 1 is "No", is Wordpress a good solution or is there something simpler?

Thank you to anyone answering.
