The best DVD authoring software is Ulead DVD Workshop 2. It's discontinued, because Ulead is gone (out of business), but it's by no means obsolete. It's still one of the best authoring programs available. So I recommend using that is you can locate it.
I'd have to see an example of what you want done -- an image of each screen. Authoring that is probably not hard, but it's often not a direct method. Authoring DVDs is a very strict/rigid process, so there are many rules of what can and cannot be done, but there are many workarounds to visually achieve what you want.
For example, that "secord half" image is another whole image that just looks like a half. And if you want to animate the bottom half moving up, that just a small transition clip. And all of the is possible in Ulead DVDWS2, whereas it's not with most other programs. DVDWS2 was intended to be a "prosumer" app with pro functions and a consumer point-and-click GUI. And it succeeded!
Put that video up here.
For a few bucks -- not much at all --- I could maybe even mock up a template that you can use. We'll see!
