Just sharing a free service that allows you to cteate your own Worpress theme in just minutes without any specific skills. Even more: you’re getting a WYSIWYG editor and you can preview your changes instantly. Absolutely no skills are required: HTML, CSS and WordPress widgets may also be kept away. Here is it: WordPress Theme Generator.
I consider it most excellent resource for WordPress newbies: everyone has the ability to customize the theme or create a new one. This site will also help you to understand WordPress basics, and further it’ll be much easier for you to understand the code.
