Currently I am working on a project that involves testing all kinds of ppl's basic computerskills and see if they are proficient enough to do so for a living.
This involves users from all age groups and varying learning capacities.

My plan was to make a flash based GUI and integrate a series of tests and tasks for the testees to perform. For some applications that will be in the suite, like typing-tests and such, I have found open source programs, mostly to spare out time and money. (its a non-profit assignment)

Now I need a way to integrate these things (or at the very least run them) from a flash environment. I also need to find a way to make a flexible GUI, that accomodates both the computer-illiterates and the more advanced users.

Any ideas on this project? (I'm just starting up, so the sheet is rather blank atm)

If anyone knows how to integrate external programs into this project, I would be very thankful as well.
