Well, Director does have a bit of a learning curve, but I don't know that it's too much more complicated than website construction ("images, cascading style sheets, and layers" oh my!). The first time I used it I created the project I needed in about five hours.
The good news is, the very smart folks at Macromedia will allow you to download a fully functional version of Director and try it out for 30 days. Do this. It might surprise you. Especially if your needs are pretty basic.
Of course, it IS expensive and I think that you may even need to buy a PC version if you want to create a cross-platform CD. So, you may want to download Dreamweaver while you're at it. If Director proves too challenging then maybe a simple web interface is the answer.
