Okay, I've been looking around and this is all I can find out about making a UI...

~I need to know XML
~I need to have some sort of software
~Found Sidl Fiddle, SidlWidl, and EQcolors ( No idea how these work)

Am I missing anything? I'm trying really hard to learn about making UIs from previous post by going to search parts of many fourms and type "Making User Interface" but doesn't show a whole lot. Could someone help share some knowledge with me so I can ascend from this newbie state, please?

Most appreciate about any response here and the time spent to view my idiotic post that probably has tons of people annoyed already from another post like this. I'm sorry about that but I have to learn and you guys seem nice enough to do some detail explaining. Thanks once again and sorry if I angered anyone
