Creating custom options page

I am creating a theme for a client and it has a custom front page that has a slider and displays the services they offer. I am looking to add an options page where the client can easily update the slider images, service titles, descriptions and images. I have seen this functionality on other themes and am having trouble trying to implement it. I have followed a few different tutorials and I understand how to add the page to the menu, but am unsure how to get the form to update the information on the front page.

Are there any tutorials out there that deal with this? I’ve looked at a few that invovle the settings API but those didn’t seem like exactly what I am looking for. I am fairly new to theme development.
