Is there any sort of program out there where you can put in a place (for example, Denver, CO) and then put in an amount of miles and have it tell you where you would end up?

No, because the result would be ambiguous: it depends on the direction you go, as well as how far. Given a direction, you can use spherical trigonometry to see where you would be after having gone a specified distance. But the problem is usually run the other way: how far is it from Denver to San Francisco? If you have a scientific calculator, there is a particularly easy formula to figure it out; it is:
cos d = sin L1 sin L2 + cos L1 cos L2 cos P, where d is the distance, expressed as an angle (mulitply the number of degrees by 60 to get nautical miles); L1 and L2 are the latitudes of the starting and ending points, and P is the difference in longitude.

Yes,
An atlas and a string.
