Hi, is there a good tool to convert a C++ project to FORTRAN?

Try a human brain.

Those things can be very useful.

Of course.
But:
1: My brain does not have the knowledge yet and I miss the time to learn C++.
2: My project does not have the means to hire a person with a qualified brain.

Consider one C++ feature, multiple inheritance - Fortran does
not have it (which is good), and there is no really clear way to
model it, unless you construct your vtabs by hand.

My guess would be that it is almost impossible to do in a way

First, a question: why "2 FORTRAN"?! Staring with ISO IEC standard document for this programming revision published in 1991, it has been "Fortran" e.g., the so-called "Fortran 90" revision to refer to that 1991 publication.
`FORTRAN` might come across as implying your interest in working with a prior version, say FORTRAN 77 and its nonstandard extensions. In year 2022, those who wish to work with such `FORTRAN` will be fewer in numbers!!
Secondly, you may want to consider "crowdsourcing" such an effort instead of seeking a tool.
For example, you can start a project on GitHub where you post the C++ code in question. Then you can request for help on this forum and also at the Fortran Discourse site (https://fortran-lang.discourse.group/) with translations to modern Fortran and chances are high several of the eager Fortran enthusiasts will chip away at the C++ code and assist with authoring modern Fortran incarnation of what this C++ code does.
I suggest you give that a try, if you can.

No, but you can create C interfaces to your code and call them from Fortran.

There are also tools such as SWIG https://github.com/swig-fortran and
shroud https://github.com/LLNL/shroud to make it easier to call C++
from Fortran.

The Rose Compiler knows Fortran and C++ and can translate backwards and
forwards between languages. They don't give any examples specifically
for C++ to Fortran, as it seems to be more a toolkit or framework
for rolling your own:
