Web Design Beginner

I am new to web design & have to create a website for me & my local organization but do not know how or where to begin. I do have MS Frontpage 2003, but it is rather difficult to do what I want to do. I am very comfortable using PowerPoint & MS Word, & want to know if there is web design software out there that works similarly to MS PP. What other software out there will let me work as effortlessly as PowerPoint does when I create my website?
Thank you.
