Seeking and advise/General question

[Richard Flame]

Hi everybody,

I have developped a big Excel template with multiple sheets to perform
some Financial analysis. However i used to program a lot more than i do
now and i'm just wondering what would be the best programming language
that i can write to perform something similar to what i'm doing now. (I
know C++ and Java and not familiar at all with .Net for example) I know
it's a lot easier to create a GUI in there languages than it is in Java
or C++.

Thank you!
