You'll have to be patient with creating your own custom theme because WordPress is widely known as incredibly easy to use and not requiring programming skill and making a custom theme is unexpectedly challenging. Hacking together a custom theme can be done within a couple hours of learning and experimentation but doing a good job of it requires a lot of WordPress-specific knowledge. WordPress has lots of functions for printing menu, page, and post content and a lot of best practices that generally take at least a few days to learn. Doing a theme that looks ok for your unique site that doesn't need sidebars, blog comments... can be fairly quick but ensuring that your theme follows all the admin dashboard settings on menu, sidebar, post, blog comments... will require significant self-study. For an experienced software developer like me, I spent a good few days studying and experimenting to get various features working in a custom WordPress theme.
