Some people open a small window first, and use the border dimensions
from that.  You could add a "Welcome" window that introduced the program.
Something that said "Welcome to MyUtility, by Colin DeWolfe", would
seamlessly give you that information.

Many people rely on knowledge of the quantities that will be placed in
the Border variables of the windows they create.  These values have not
changed in 2.0, though I'll warn you that Intuition now renders into
ALL the pixels that those values declare.

The font that your window will get (if it's on the Workbench screen) is
GfxBase->DefaultFont for the text that will be contained, and the
WorkbenchScreen->Font for the title bar.  The title-bar's height will
be WorkbenchScreen->WBorTop + WorkbenchScreen->Font->ta_YSize + 1.

>3)  how does one find out in C whether you were launced from workbench or CLI?

The standard argc variable is zero from the Workbench, and always at least
one from the CLI.  You can use your workbench startup message to get
Workbench arguments, and argv[] to get your CLI arguments.
