Ruby and GUI programming (Easiest Setup)

I'm relatively new to Ruby and I'm totally confused as to what the best/easiest setup is. What I want to do is write GUI programs and in particular convert a RealBasic program (that I wrote) that accesses and manipulates MySql databases. I'm a Windows Vista user.

Coming from RealBasic everything was contained in the one program so there wasn't any confusing decisions to make as regards GUI librabry, editor etc.

Could somebody list or itemise in simple terms what components are required in order to create a Ruby GUI program.

Thanks in advance.

Well the main GUI toolkit would be Tk, here is a list of a few more.. plus any resources that may help

I'm not a lover of GUI programming personally, but if you have any specific questions then please don't hesitate to ask

Hope that helps in any way, feel free to ask for more if it doesn't

Thanks for your suggestions and I'll certainly take a look at each site.

What I was trying to glean was more along the lines of what's the best or most productive package ie. Ruby, with this editor (because), this GUI kit (because)... I'm sure there are users out there that have got themselves setup nicely and are no longer going backwards and forwards changing between different components. I hope this all makes sense.

Again, I appreciate your input.

I see, like i said i don't do any GUI stuff, but i hope someone else can assist you in this matter. When i code raw Ruby i either use vim on *nix or Komodo...

Although i haven't used any GUI kits i did play with Tk quite some time ago, it seemed friendly enough to me.
