No, they could be left in C or Pro*C, but you have to use Visual C++ 1.5.

I think they are more difficult:
The user exits in Forms 4.5 are in a DLL, so you could not use
all standard C-Calls (e.g. sprintf() is not available). Debugging
is impossible (under Forms 3.0 is is also nearly impossible).
And you could not use printf() (you must use fprintf() to a file,
to get hand-coded debugging information).

I use the books from Oracle.
