Solution 1

Here's how you do it:
1) Design
2) Code
3) Test

Your question is too vague and broad to give a specific answer. What are you having problems with? databases? mapping? least distance calculations? building a UI? . . .

Given the coordinates of a hospital and the person holding the phone calculating the straight-line distance between the two is simple math. But I get the feeling that's not what you are looking for. You may be asking for the driving distance. Determining the driving distance implies you will also be determining an acceptable path to take. Path finding algorithms area specialized problem type of their own.

Try googles Geo Code libraries, you will have to rewrite them for .Net
