Memory for Grails:
https://grails.org/wiki/FAQ
Search for memory on the Wiki page. However, even for trivial
applications it appears to consume 512 MB. Since you didn't say what
version of Java you're running, it's hard to tell you what (if any)
memory settings you'll need.
Tomcat by itself uses very little memory
Memory for Vaadin:
https://vaadin.com/wiki/-/wiki/main/Scalable+web+applications
There are several pieces of information concerning memory usage.
Application memory in general:
The above two links are for general information. The memory actually
used is highly dependent on your application (see notes in the second
link above). The best way to determine this is to measure (VisualVM,
Java Mission Control, etc.).
Memory for PostgreSQL:
https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server
http://www.postgresql.org/docs/9.5/static/runtime-config-resource.html
Again, this appears to be in part connection and schema dependent.
Measurement is your only true option.
In short, use the above links to get yourself into the ballpark. Then
run your application under load and measure. Tomcat is probably the
least resource-intensive component of your architecture.
The above links are the result of less than 5 minutes of searching /
skimming using Google.
. . . just my two cents
