I cracked it and got an initial build working by taking apart Defensive Weapon Training feat. Now I just need to add conditions for Grapple and Spell as selections and to test that Natural special condition works properly. I'll post the finished result once I have those sorted out. Working so far:

      ~ If we're disabled, do nothing
      doneif (tagis[Helper.FtDisable] <> 0)

      ~ If we haven't chosen anything, get out now
      doneif (field[usrChosen1].ischosen = 0)

      ~get the wFtrGroup tag from our choice
      perform field[usrChosen1].chosen.pulltags[wFtrGroup.?]

      ~if we didn't find a wFtrGroup tag, there's nothing more we can do
      doneif (tagis[wFtrGroup.?] = 0)	  
	  
      ~ If we are a bonus feat which ignores pre-reqs, we don't want our weapons
      ~ to complain when they don't find those pre-reqs we skipped.
      if (tagis[thing.skipprereq] <> 0) then
        perform assign[Broadcast.NoPWepFocu]
        endif

      ~ Assign the appropriate tag to all weapons that meet the criteria
      var id as string
      var name as string

      call fTargetId

      foreach pick in hero from BaseWep
        if (eachpick.tagmatch[wFtrGroup,wFtrGroup,initial] <> 0) then
          perform eachpick.assign[Broadcast.WepFocus]
          perform eachpick.pulltags[WepFocus.?]
          perform eachpick.pushtags[Broadcast.?]
          endif
        nexteach
      perform hero.pushtags[WepFocus.?]

      ~ Set our 'short name'
      field[shortname].text = "Focus: " & name
      field[sbName].text = "Weapon Focus (" & lowercase(name) & ")"

      ~ If the selected weapon is a natural weapon, then apply the Hero.NatWpFocus
      ~ tag to the hero. We do this here so that the hero doesn't actually have
      ~ to have such a weapon on their character in order to get the tag and
      ~ qualify for pre-reqs based on it. For example, a Druid/Monk may want
      ~ to take Weapon Focus (Claw) in order to take Feral Combat Training, but
      ~ may not actually have claws most of the time (only when wild shaped).
      if (field[usrChosen1].chosen.tagis[wFtrGroup.Natural] <> 0) then
        perform hero.assign[Hero.NatWpFocus]
        endif

      ~ Choosing Grapple gives us a bonus on those checks
      if (field[usrChosen1].chosen.tagis[thingid.wGrapple] <> 0) then
        ~ Add a +1 bonus to the Grapple CMB
        hero.child[manGrapple].field[cmbBonus].value += 1
        endif

      ~ This is chiefly for the Low Templar PrC's pre-req (which requires weapon
      ~ focus in any martial weapon), but also checking Simple and Exotic as
      ~ well in case those are needed in the future.
      if (tagis[wProfReq.Simple] <> 0) then
        perform hero.assign[Hero.SimWpFocus]
        endif

      if (tagis[wProfReq.Martial] <> 0) then
        perform hero.assign[Hero.MrtWpFocus]
        endif

      if (tagis[wProfReq.Exotic] <> 0) then
        perform hero.assign[Hero.ExoWpFocus]
        endif
