You can use an edit box and macro substitution.
Capture the keys in the editbox's keypress and watch for enter (nkeycode = 13). If nkeycode = 13 then
mycommand = this.value
&mycommand
this.value = space(0)

It is important to have an error handler for this, or once your command produces an error, the control will start acting finicky.
