Jim has given you good basic advice.
C25K is a great plan for getting started.
When you go to the running shoe store, tell them what you are doing and what your goals are. Take/wear your current shoes as they may provide useful clues about what does/does not work for you.

Hi! Would someone be so kind as to link the best running schedule for someone who can run 1/4 of a mile before getting tired.
Or my feet/leg hurts.
Or the side of my stomach hurts.
These are all symptoms of going too fast (or too far but more likely too fast) for your current state of conditioning. C25K can help you correct these problems by slowing down and running shorter intervals.

Running at normal pace.
I'm 90-100 pounds.
Whose "normal pace"? When learning to run distance, you need to slow down from what you might consider a normal pace.
You weigh 90-100 pounds? Or are you overweight by that amount? (We get both kinds here.) My guess is overweight because of the range. Which may be another reason to slow down, and be patient.
Goal is to be able to run 3 miles straight.
Please, a schedule that reaches the 3 mile goal the QUICKEST.
Getting there the QUICKEST is also the most likely way to end up injured. You want to get there in a moderate, controlled fashion, which is another feature of C25K.
Good luck with your shoe search and your running goals.
