Custom Theme Creation

Hello all, I’d like to design a custom theme, but I have no experience coding in PHP, but I’d like to make a theme with flash animations for some buttons I’d like to put on my template. For Example I’d have a Header then a buttons bar such as topics/categories and or archives which will open up a new page which will list the topics/categories and archives respectively. My main question is, how hard would it be to make this template/theme workable and possible for someone who has no experience whatsoever in PHP. Or is it possible to edit a current theme without coding, but in DreamWeaver.
