Labview project (for fun) - help!

[thecoldfact]

Hi
I thought I would reach myself some labview (as I have never played with it) and I thought I would do a project (I haven't seen one yet like this) which is a sallen and key calculator similar to the one found on www dot analog dot com (the filter wizard).
So I need help. Either;
1. Has anyone done this before and is it as straight forward as a I think it could be
2. Has anyone seen a similar program which I could look at (as I haven't found one)

Any help is much appreciated. Thank you
