Having troubles with my custom menu system

First off, hi everyone! I'm new on this forum and I really need some help. 

I have done some scripting in the past with different languages

and while I can understand bits and pieces from Ruby, I can't figure out how to script my own menu system

What I need is one of the most simplest menu systems there probably is and still can't find any tutorials that help me do that.

(Or maybe I just don't understand the tutorials that well...)

Basically the menu constructs of a centered BG image, 4 buttons and a higlighter. (buttons being, Back, Journal, Save, Quit)

It's navigated with Up and Down arrows and should pause scripts possibly running atm on the background.

If someone feels bored and wants to help that would be much appreciated <3

I'll attach a picture of the menu system I made in Photoshop.

Why is Back crossed out? Is THAT your selector? Usually a line through something means it's not available, not that you've currently got it selected.

Thanks for moving this to the appropriate location :D  

And yea, that's the selector atm, although now that you mention it I could use a circular selector.. But that was just something I made quickly :p

Actually I happened to solve this myself... :D

Wasn't that hard in the end actually
