Looking for some ideas, perhaps a programmer

[emm]

I'm trying to make a program for myself that can handle some of the simple math in certain poker situations, displaying some figures on the screen for me, percentages, odds, etc.

To start, I need the program to know what cards I have and what cards are on the board. Then the program does the math and makes the output (for instance, I have AhKh, the board is xh xh xd...program then tells me that I have xx.x% chance to hit the flush on turn)

If that makes sense to you, and you have a clue about programming, could you please answer the following questions:

Should this program screen scrape to recognize the cards, or dig into the incoming stream of data, wherever that is, to pick up the known cards?

What programming language do you think is most appropriate for functions like this?
