Migrating from VBA Excel 2003

Question

I have a series of big excel files that work like a program, but I hate beeing tied up (stuck in VBA for excel 2003), so...

Whats the best way to implement a gui over a excel vba program (office 2003)? (are there any tools for that... I want to move away from the office suite, but still have it in the background)

Or what's the easiest alternative for migrating this code to a more open language. Any ideias?
